So

as some of you know I plan to test for my J.S. at next year's Blade show.

but first I have to pass the performance test with a Master Smith (See the testing rules HERE )


so obviously I need to make a special knife for the occasion, three of them, to be exact.

my plan is to finish out all three the same and do the full test in my shop twice before I do it for real with the M.S.

Keep in mind that there are a few things I will do differently SPECIFICALLY because this knife is meant to be bent.

Starting out, I forge the point in and draw out a little bit to establish a taper.

Forge the bevels in place and knock down the choil

pretty much forged to the shape I want here

first couple passes on the grinder

it's important that the knives be almost exactly the same, so I have a good reference of how the third will perform in the actual test

another THOROUGH normalization cycle

apply the clay for HT, normally I want 1/3 of the blade surface hard, but for the performance test I really only want a small portion hardened

Tempered twice at about 500 F, going for a good bit softer and springier than I usually want. 56 RC should be about what I want. Testing will show for sure

I plan to do video.

there's a edge test I've been doing for a while that Aldo keeps bugging me to video for him. I drive a nail into a 2x4 and chop through it. I plan to do that at least once. just for him.


I probably should have mentioned some specs

these are made from Aldo's last batch of 1084FG 1/4 x 1 1/2

blade length is 9.5" and O/A is 14.5"

also I plan to fully round the spine....
 
They look good, Stephan.

Grind them thin, 3/16" or less at the spine, with a lot of taper to the point.
Most blades that fail the bend are too thick and have no flex.

It's interesting you doing three just a like. What if the first one fails?;)

depends on HOW it fails.

if it's a HT failure it may be just a tempering issue I can resolve with the second.

but from my experience with this 1084 I won't have any problems.
 
Looking good Stephan. How long before you test?

not 100% sure, I am HOPING to test at Bowie (Ron Clairbourne)'s Hammer In which is usually Mid Sept but haven't been able to get in touch with him to confirm a date so I can try and set up with a MS.
 
Stephan I really do not think you will have anything to worry about, but good luck anyway. :)
