Oh man! I was beginning to think you ran out of steel or started baking pizza and steak in the kilns! I see a couple interesting blade shapes there! This is gonna be cool!
-X
Ohhh agreed. I cant wait to see how these turn out!
I was going through the pictures of kitchen knives on your site last weekend. Felt like I was looking at a Victoria Secret catalog 😂
Glad to see you working on new things. 200 backpacker's! And I only have 3.....
ohh that mix is looking good, maybe i can convince my gf to get me a fairly for valentines day haha
Think alot of us have been waiting on this batch. Dan is shaking things up. Congrats on the back packers. I keep a backpacker or ti bottle opener on a neck lanyard when ever i go cycling or running. Always nice to know i have a dependable blade for any situation, and no matter how slimey i get, it wont effect the blade.
Hey Daniel! How'd did Hartsfield get a hamon on A2??
![]()
There are few ways to achieve a Hamone. First is the selective insulation of the steel. the entire blade is brought up to temp and exposed parts cool fast enough to harden while the insulated portions become normalized.
A2 is an air hardening steel and Clay coating will not sufficiently slow the cooling to keep the entire blade from decomposing into Martensite (hardening) so clay does not work.
The second way is to walk the line between heat extraction and cross-section. Meaning you take a given steel and heat it to a precise point. The volume of heat to be extracted is tuned to the point where all parts over a certain thickness normalize and the parts under that thickness harden.
A2 is extremely deep hardening steel and does not respond to this method.
Another method is to selectively austenize. This will let you harden only the portion you heat. The limitation on this you can't soak the steel. This work fine for steel with little to dissolve i.e. low alloy short soak steels.
A2 has a minimum soak time of 20 minutes at full heat. thats what it takes to get all those alloy elements to dissolve into solution. If you quench as soon at full heat is reached you really dont get all the benefits that A2 can provide. It doesnt realize the steels potential though it can yield a notable difference in hardness between the two areas. A difference in hardness does not a Hamone make...For me the definition of a Hamone includes a plainly visible transition of structure type within the steel. that brings me to the last hurtle.
That last hurtle for A2 is even when you get it differentially hardened The Hamone doesnt show up it is practically invisible no matter how you polish it or etch it (that I know of)
The colors and intensity of Phils Hamone on top of the course state he leaves the blades in, tell me they are cosmetic and his A2 blades are most likely through hardened.
I believe that Adrian Ko stated on the forum at one time years ago that Phil himself admitted they were cosmetic in an interview.
