Anyone ever heard of this thing? "The Double Grinder"

Hello:

I value my eyesight more than that..even with superlative eye/face protection I would not use one after seeing all those bits of steel flying UPward.. Plus I can see some serious entanglement problems with those exposed belts and all......

Yeah, I remember Rob Frink talking about the liability issues with tool rests...

And he has cut the time required for making custom handmade knives from 2 days to less than 10 minutes in the hands of an expert.

Nope, it claims to cut the production of making the knife itself down, not just the grinding, as you can tell from the quote I've taken off the site. About the week claim, yes I was exaggerating unless you work on multible knives at any given time. But it does generally take atleast 10-16 hours for even just the basic knives.

I agree with Stacey Apelt . Way too much money thats like 4 kmg machines. It takes only a few min to screw up a blade for me either way lol

I don't think you can generalize the time it takes, each person is different. Not including heat treating, I know several people who can grind and put together a knife in an afternoon.

Also, you have read to above the highlighting to put the "claim" into perspective:

It was noon and the other knife maker had an appointment at 3:00 and so it would be impossible to see a knife being created. Bill turned on the machine as his friend watched and profiled and hollow grind the file into a fully formed knife and then asked "Now what time is it?" "12:07" the man said as he sat down hard on the ground shocked at the small amount of time involved with creating a custom handmade knife. "It would take me two days to reach that stage with a knife with my own equipment. You did it in seven minutes. How much is that machine? I have to have one."

The point to all of this is that your time into a knife has nothing to do with another maker's time. Some people spend weeks, months or years on one knife. Others might spend only hours or, I suppose, minutes. I'd bet money that this guy with his 7 minute double grinding can't put out a ground blade as fast as George Herron could with just a single contact wheel and people actually know his name.

I visited the Late Jimmy Lile's shop back in 1979. Jimmy was making a Limited Edition Dagger for the Arkansas State Police. He demonstrated how he could grind both sides and both edges of a dagger in about mere minutes. He was using a double grinder. His grinders were running such that the sparks went toward the floor. One wheel ran clockwise and the other ran counter clockwise. I don't know any thing patents but this was in 1979 and Jimmy had been using this machine for a long time before He showed it to me. Nothing new about this grinder.
