What is Burl Wood? Get To Know a Wood Feature, Part 3

 In order to craft the best handmade wood iPhone and Pixel cases possible, KerfCase offers a wide variety of wood species, some of which incorporate unique features that are especially prized.  

If you're not a woodworker, but you want to learn more about what makes some wood cuts (and some cases) especially beautiful, enjoy our four-part series on unique wood features!

What is it about burl wood that makes it so beautiful and prized?  Read on to find out.

 

No two pieces of wood are alike.  One of the great joys of working with wood is knowing that no matter if you're carving a Greek god or nailing together a bookshelf, your creation will be 100% unique.  Like snowflakes and fingerprints, the grain pattern that forms in trees never perfectly repeats, so each board will have its own unique appearance.

This uniqueness exists on a spectrum; many cuts of wood look almost alike, the differences only perceptible to a seasoned viewer, or a microscope.  For craftsmen looking for uniformity across a large project, this is a good thing.  But we at KerfCase are specialty woodworkers, looking for the most unique and interesting pieces of wood around to use in our truly one-of-a-kind cases.  So let's take a look at the special things that we look out for in our wood selection, zooming in this week on burl wood.

Burls Just Wanna Have Fun

 

If you sort a wood iPhone case collection by price, you’ll notice that the most expensive KerfCase money can buy is the Amboyna Burl case.  At a wallet-walloping $409 starting price, it handily beats out other interesting wood types on price, such as our spalted maple and figured walnut cases.  What is it about burls that makes them so prized (and so expensive)?  Let's find out.

 

Just like pearls (which I tried and failed to make into a pun for the above heading), burls are something beautiful, made from something annoying.  When irritants are introduced into an oyster’s body, it sequesters off the offending particles in successive layers of calcium carbonate, eventually producing a lustrous, iridescent jewel.

 Tree Burl
You could call burls "the pearls of the forest", but that would be confusing.

 

Similarly, an irritating fungus or insect habitat can sometimes cause a response in a living tree, rapidly creating a warty mass of tissue, covered in bark, to protect the inflamed area.

 Too Much Burl
Sometimes they go way overboard.

 

These weird tree warts would be strange but unremarkable, were it not for their fascinating inner makeup.  Most wood grain runs in a straight line and is rather predictable, but in a burl, the grain twists and spirals in surprising ways, creating a complex knot of grain that is uniquely strong, and when viewed in cross-section, absolutely gorgeous.

Burl Meets World

 

 For obvious reasons, burl wood is rightly prized by furniture makers, luthiers, and all sorts of specialty woodworkers for its stunning appearance and unique structural properties.  You see burl lining nice cabinets, luxury automobiles, and even the sounding boards of guitars!

 
Gnarly, in more ways than one.

 

Adding to burl wood’s value is its rarity.  Spalted wood (and pearls, for that matter), can be “farmed” by fostering the right environment for the useful feature to grow.  While scientists have a rough idea of how burls are formed, no one has succeeded in growing them in a controlled environment so far.  Meaning this rare grain can only be found in the wild.

 Unfortunately, the market forces of scarcity and demand have created “burl poachers:” people who mutilate protected trees to harvest the valuable wood, leaving horrible scars behind.

A Burl to Call My Own

 Hopefully, this shines a light on why an iPhone case made of burl wood would be so special!  Amboyna burl is our cream of the crop, owing to its deep maroon coloring and stunning grain pattern.  It is harvested responsibly and sustainably from the padauk wood it grows from in southeast Asia, and its many holes and checks are stabilized with resin before we carve it into a case and sand and finish it to a beautiful sheen.

 

 KerfCase Amboyna Burl Wood iPhone Case for iPhone 7, iPhone 7 Plus

For those hoping to get in on the fun without spending quite as much on an iPhone case, our Yellow Box burl comes strongly recommended.

We have a few new burl wood cuts coming soon that we can’t wait to show you!  Keep an eye on our Facebook/Instagram to get the latest updates.  You can also contact us to get early access to our exclusive and rare wood cuts though our Specialty Woods mailing list.

 The best part of my job is helping people choose their perfect case, so please contact me if you’d like to see our available wood, and choose a grain pattern that fits you the best.  Especially with burls, it’s important to us that you see the case you’re getting before we start to carve it.  Let me know if you'd like a burl Pixel case too!

 

What will your next case be?

 

 Hopefully you enjoyed my burl talk, and stay tuned for our series wrapup next week with a discussion of the impressive-sounding chatoyance!

"This case is a work of art." -Kurt

"I received my new phone case, and it is beautiful...a work of art!" -Dan

"I've never liked a case before. I've tried some different rubber and plastic cases and always end up taking it off within a couple days. This case, however, I will never take off. This is by far the best looking and best feeling case I've ever owned. Also loved the packaging touch. Keep up the good work, I will definitely be buying more in the future." - Yasir S

"The world could use more good design and less plastic!" - John C

"I just got my new Kerf case, and it’s beautiful! My company logo on the back came out sweet! And, I can charge the phone through the case on a Qi pad, which makes it even better. You all should be proud of your craftsmanship. " - Leroy N

"I received my Kerf Case this afternoon and I am really pleased with it! I love how it envelopes the phone and has a feel that is easy to hold. The buttons work great and I like that the silence button is recessed, it isn’t likely to be bumped. I really appreciate the job you did on the graphic on the back. Thanks for your work on this!"- Nels K

"This is the first time I will be using an iPhone case - ever!
I did my homework - I looked at many manufacturers online (none of them seemed worthy). This is a huge vote of confidence and testament to what I imagine will be amazing craftsmanship."- Matt K

"I just have received your product. I just couldn't be happier. It is much more than what I expected. There are few alternatives in terms of google Pixel phone case but your creation is much much better choice. Thank you for creating such an excellent product." - Y Ito

"In the end, what swung it for was the fact you were a small local business that sourced within your local community. Even though I live in Glasgow, Scotland, this really was important and I liked the fact your company was proud of your area, the resources it has and your product. The choice of woods was also pretty cool and at one point is was very torn between the walnut and the rosewood. I ended up opting for the walnut - very much looking forward to getting it on my new iPhone X." -Derek S

"I just received my iPhone case today and it's stunning, keep up the good work!" - Andrew D

"I really do appreciate the help that you guys have done, i know i was frustrated at first. But i do really appreciate companies that really help out with their products. means a lot from someone like me who has had multiple things sit broken in my room because companies would not help out." - Chris W

"I left my phone on the vinyl roof of my car (let’s not discuss that) and it finally flew off as I drove and landed on a busy street. When I was finally able to locate and retrieve it, it had been run over by a large truck and dragged more than 300 feet under the tire. When the truck turned, the case, phone, and wood separated and I found them about 20 feet from each other. Remarkably, my iPhone is fine! Also remarkably, so is the spalted maple backing! However, the steel frame, having done its job well, is now bent (but not mangled). I don’t know if any other case made out of any other material would have done as good a job." -Ben W

"Just received my Alloy case for iPhone 7 and I’m very impressed with the quality of the case. I will definitely purchase more products from your company and will recommend Kerf Case to family and friends. Thanks for a great product." - Gohar N

"As a woodworker I really appreciate the unique iPhone cases you craft. This is my second case. I bought the new iPhone 7 plus, so I had to order another one as soon as possible. I can't tell you how many comments I have received, with the main comment "that's so cool" and " really that's all wood? Thanks and keep up the good work." - Clarke

"I’m a woodworking hobbyist and was really impressed with your product! I have told several friends about it already and will be sharing links and pictures with them when it comes in! Thanks for making these." -B

"I received my phone case yesterday morning, and after the first 24 hours with it my first impression is wow! The quality of this case is beyond my expectation. It's so smooth and wonderfully sanded, I can smell the wood and that is one of my favorite parts of it. I love the little attention to detail that most wood phone cases don't have, like wood buttons instead of rubber. Being a man in the military I take extreme pleasure in attention to detail and your product definitely delivered. Thank you so much for not disappointing me! Good luck with your company I'll be rooting for you!" Very Respectfully, Petty Officer 3rd Class Dehart, Nathan D.

"I received my case last week and after seeing how amazingly made it was I had to order one for my wife right away. Thank you for making such and outstanding product!" - Daniel

"The spalted maple iPhone SE case I just received is wonderful!! A true work of art and totally functional. Love it! Thanks so much. Will recommend to everyone and when it's new iPhone time for me it will always be Kerf case time." - Eddie

"You just can't replicate that depth of color and texture with man-made materials. It brings my glass rectangle addiction one step back into the natural world, and I'll take that wherever I can get it." - Stephanie

"Thank you for making such an awesome product both durable and stylish. You have helped in every way I've needed and in an expeditious way....something you can't find in an owner of a business these days. I greatly appreciate everything." - Jake G Hampu

"I just wanted to let you know that I received my case today and it is quite possibly most beautiful iPhone case I've ever seen! I did a lot of research on wood phone cases and settled on Kerf Case because of the quality—I was not disappointed. The care that went into crafting and shipping the case is evident and I couldn't be happier with my purchase. Thanks for creating such a wonderful product!"- Kirstin

"Apologies for the delay in replying, but it was somewhat intentional. I wanted to wait until we received our cases yesterday. I am more than impressed with the craftsmanship that you and your staff put towards your products. The cases are beautiful and well worth what we paid for them. Thank you again. I will have no problems referring friends to KERF, who have as much of an appreciation for natural hand crafted products as I do." - Kyle Elias, BScH, DVM 

"They are going to become my holiday gift this season ....for all my people....Great product. Very original." - Christopher Bardasian

"Now that's customer service. Thanks Ben I appreciate the attention to detail you guys have with your business plan. No questions but I will tell you that you've earned my respect with the speed, efficiency and quality products you're providing with your customers." - Mark Wilson

"Just wanted to reach out and thank you again- I got my cases back this week and they are beautifully repaired (or replaced, I can't even tell)! Please give Cat my thanks as well for her craftsmanship. I was already a big Kerf fan and repeat customer but will definitely keep coming back thanks to your outstanding service and support. You guys rock, and your products are beautiful. Thanks so much." - Courtney Sanford

"Thank you for your direct contact. This morning I picked up the case from the German customs office. And let me tell you this case is amazing! Thank you so much, you guys did a great job." - Stefan

"Well beyond expectations. Craftsmanship is as close to perfection as possible. Customer service is impeccable and prices are lower than competitors who make inferior products." - Robert W
