Heat Treat Service
Heat Treat Service
We offer a heat treatment service, ideally for our billets but if its a steel we use often, we will heat treat from other sources. For stainless steel please contact us and we will check the heat treat process and quote directly. Please see options below for pricing. Please work top down through the options. The first of each steel type includes a flat rate cost for running the kiln, additional blanks in the same batch are far cheaper. If the options don't seem to fit your requirements or if you have a large quantity please send us an email and we can work our what's best. If you are on a tight budget we may be able to fit one or two in with another batch.
Blanks should be rough profiled at full thickness with any required holes drilled. Stainless or wrought iron clad San-Mai requires 45 degree bevels round the entire profile as described in the heat treat info on the listings. We are happy to do that for you if needed but please leave your profile over-sized so it can be neatened up post heat treat. We guarantee a straight (within reason) and crack free blade and any potential problem areas will be discussed beforehand. Tempering will be done to our standard hardness for each steel and knife type, please leave a note on the order or email us if you have any specific requirements.
Please contact us directly if you have any questions. Once we have received your order, an email will be sent with a shipping label and lead time. Please leave a note on the order if you wish to drop off / collect your blanks. (Recommended - based in TN29).

Let customers speak for us
from 17 reviewsI purchased a custom knife from Korben. Korben took me through the process step by step from drawing different knife shapes and explaining the pros and cons to what designs I was looking at. This explanation included the steel types and the how the handle grains would catch the light. The knife arrived a few days ago and even the box it came in was a presentation itself. As I picked up the knife, I was quite impressed with the build quality and finish. The hamon line was remarkable and well defined. The edge almost fell through a sheet of paper by its own weight. I have many custom knives and this one is by far my new favorite.
Brilliant billets.
Brilliant customer service.
I've used dozens of them and they have all been superb.
Korben is a gent
Amazing knife maker, very friendly and knowledgeable. I had a custom knife made for me a year or so ago and its been a super reliable and beautiful knife. The experience was fantastic, very flexible and professional throughout the whole process. they also do amazing knife sharpening jigs!
The knives are so much more than anyone could ever ask for. Absolutely beautiful
I was excited to hear about KWB Knives as my husband really appreciates a good knife and I like to support local businesses. Korben was helpful and informative throughout the process of agreeing a design and production even though I was buying at entry level. This is a company very much worth supporting; you’ll have a great experience from first contact and every time you look at, let alone use, the knife for evermore. Thanks!
Sorry for the delay in review! Absolute 1 of a kind craftsman. You can see for yourself in the designs the style is outrageous but quality is just as good. Will take the time needed to make sure it’s right and won’t rush which is what you want when you’re looking at pieces like these. All the best.
A decision to get a custom kitchen knife made just for me came with some risk due to many choices out there. When I starting vetting Korben at KWB Knives it included checking out his work and style, of course. But, for me it was more about responses to my questions and how well he could connect to my vision. Well, he certainly has a knack and ability to listen well and then translate that to a perfectly forged to finish knife JUST for me!
He kept me updated from early design process, forging, grinding/polishing, handle material choices to assembly and finishes! As for performance, it is sharp as a razor, has the "just right" weight and balance and is of an appearance level that has me want to display it! Truly a fantastic experience with Korben at KWB Knives!
I was so glad I reached out to KWB Knives for the custom project I had in mind. From the beginning Korben was enthusiastic & supportive of what I wanted. Communication was excellent & his willingness to accommodate fine detail changes as the process went along was so welcome.
The build quality & aesthetic of the knife is just exceptional & hits all the specs I wanted.
‘What was this knife?’ I hear you say!
It was a screen accurate version of the Crocodile Dundee Bowie Knife 🐊
If you want a custom blade, KWB Knives should be at the top of your list!
Thank you Korben for the labour of love this became & it would be remiss of me not to also mention Korbens occasional colab partner Adam from Nord Knives who I understand spent a lot of time hand-sanding the blade. Your effort is also greatly appreciated!
All best wishes from a very happy customer!
Korben made a nakiri for me and made every aspect of the knife I asked for come to life! The finished product is truly something special👏🏼
I reached out to Korben after discovering him on Instagram and loved all of his amazing photos and knife work! I was looking for a custom knife for my wife and he really did he deliver exactly what we were looking for! He worked with us through every step to make sure we got exactly what we wanted. He is very meticulous and his attention to detail is exceptional. If anybody asked me where to get a custom knife I would recommend KWB Knives hands down best experience ever! Thanks Korben!
Ordered a custom knife a little while back and seriously not dissapointed. The craftsmanship is beautiful and and the knife is extremely sharp. As a proffesional chef of almost 10 years I've seen quite a few knifes and this one is among the best. KWB worked with me every step of the way from the length, the style, the edge, and even got to choose the wood for the handle too! 10 out 10 would recommend to anyone wanted a customized blade!
I absolutely love my knife. Thank you so much. Communication, professionalism, skill & quality all 5 star.
KWB are extremely professional, courteous and talented. The knives are handmade with such skilled craftmanship. Extremely knowledgable and would 100% recommend. Currently waiting on my 3rd knife to be made, would not go anywhere else.
I have a collection of knives both Japanese imports and British bespoke made and I have to say I was blown away from start to finish with the craftsmanship from KWB. My knife from KWB is head an shoulders above the rest. The knives are so unique, nothing like I had seen before. Razor sharp with a unique lightning bolt effect running through the blade, making a stunning and eye catching piece to add to my collection. I was kept updated well throughout the process and felt I could ask questions and make suggestions whenever needed. Korben is a master in his craft and would highly recommend investing a piece from him.
What can I say but, WOW!!
The is is my second knife from KWBKnives and I can honestly say, they are my favourite knives (I have over 800!!) They really are at a point where art meets functionality! They have no issues with being thrown in at the deep end and coming out gleaming. The shell pattern and grain structure are a pleasure just to look at!
The edge strength and sharpness retention is amazing. I haven’t even had to dress them up with a strop after a use yet. They’re still popping the hairs off of my arm.
I cannot sing Korben’s praise enough! From his attention to detail, to his involvement with you in the process and listening to all of your requests. He also has an encyclopaedic knowledge of suggestions and he isn’t afraid to try things. His handles fit so well in the hand, that they make it a pleasure and ease to work with.
I’ve already got a deposit in for #3 and I cannot wait to work with him and see what amazing creation he comes forth with!
Thank you Korben!!
