Thanks for the kind words!
Awesome work!Very nice design!I may have missed this in your post ShoerFast but do you have any idea what the finished blade would work out to on the Rockwell C scale?
ShoerFast,there is no Tool Forum yet per say. I have been asking for one but this thread named Tool Forum in the Chainsaw Forum will have to do until the powers that be can justify a separate forum for tools.So if you have anything tool related we would love to see it here
Thanks

The blade showen is etched in a mixture of HC-acid, ferric chloride and farris-chloride. The etching solution attacks tempered-martensite and austensite at different rates.
Mentioning this as it's leaves a distinct pattern in the steel, looks like wood-grain sort of if you see it?
The close-ups show an honest teat-treat, as the spine is unhardened, and each layer towards the cutting edge is progressively harder.
This knife is has a soft back/spine of about 35RC and the cutting edge is in the lower 60's , with ever shade of hardness in-between.
The transition zones are key to a knife that will not fail in the most extreme use.
Extremely nice work Shoerfast, I mean impressive! A.J. Russell one of the nations largest knife/collector dealers is just south of me, I've got to see a lot of custom knives over the years, your work is very,very impressive,especially the metal treatment. How would it compare to D2 or A2 as far as keeping an edge. For years I used high quality carbon steel knives, then lost my mind and switched to stainless for a few years and now am back to my senses using high carbon again. Can't beat them for all around useage/edge holding and ease of sharpening.
Thanks for sharing, a true craftsman!
Testing is another part of this that I truly enjoy!
Knives made out of 5160 and 52100 steels, forged to have a very fine grain structure will take a edge quicker and be a sharper edge then most steels.
To give you an idea, a 20 year old Buck #119 (most would call a very good cutting knife?) will make about 8-10 cuts in 3/4" Manila rope before cutting resistance/ware slow the knife down.
A good 52100 knife will make around 80 cuts before going dull.
There was a seminar at the 07 Blade show describing the process, truthfully, I do not know if this would work on others steel? But have not see another steel out perform 52100 steels.
Here is the start of the lecture if interested?
