Here's a knife you won't see anywhere else, the prototype for my Sumo design. It is made of slightly thinner 1/8" stock and the steel is 420 stainless, OAL is 5.25 inches and blade length is a very fat 2 inches. I used a lesser grade of steel to see how the design would feel in the hand and to test the cord wrap channels before going to the more expensive and thicker S30v.
The knife is V ground with false edge grinds. Comes with a kydex sheath and removable mini teklok belt clip. I don't have a metal "PROTO" stamp but the card is written to indicate that it's a prototype.
The price will be $175 plus $10 shipping in the US, $26 Express Mail shipping for international.
Hey DB how did you get that cool black coat over your Ringthing?That is very cool.
Another blade, very cool.
Good luck all.
Almost wet myself when I saw the Pingie notice. I have been drooling over the Sumos for a while and actually thought you stopped making them.
Go #36! =-]
There's no coating on my RingThing; just really dramatic lighting. :)
OK very cool lighting but a black coat would be pretty sweet.
Oh my god- that is the most beautiful thing I've seen....I must have it....(saying a little prayer to the lottery gods...)
very excited to see this in the lottery! I'll keep my fingers crossed. Can I ask you about the steel though? I totally understand that this is a prototype, and why you'd use a less expensive steel, but will this 420 blade stand up to daily use? Has it been heat treated to a working blade hardness? I'm sure others would be mortified that I wouldn't keep this in a glass case if I was lucky enough to win it, but my personal philosophy is that tools are there to be used (yes, even the amazing works of art you build. I just want to make sure that this is a user and not just something to keep in the safe. Your thoughts would be greatly appreciated!
The steel is not as fancy as S30v but 420 is a respectable cutlery steel and has better stainless qualities than S30v. It is heat treated to 58 Rockwell so will have decent edge holding. In addition, this blade is ground pretty thin so it's a good slicer and will be easy to sharpen.
I can not wait for the production pieces to come out. This will be a perfect work tool for me. as a bicycle mechanic we need to cut things quickly and usually one handed this will serve well.
Hehe, actually this piece is two years old. I already did the small run of the Sumos two years ago. I had this one left over and just recently finished it. I will have several more Sumos in S30v coming this fall though. They are all getting DLC coated.
420J2 or 420HC? There is actually quite a difference, since HC (high carbon) has about twice the carbon and would be preferable for a blade. I'm betting it's HC given the hardness you quoted. Just wanted to know out of curiosity. 420 HC is very similar to the steel Buck uses.
Yup, exactly. 420HC.
That's one sweet piece, Peter! Hope you decide to make more of the Sumo.
