Thread: spyderco hone

thanks for the help guys, the 320 seems to work but boy is it slow.

I gave up trying to use to the D8C on Spyderco hones.
Although it left my D8C with a nice smooth surface for
lapping naturals, I couldn't get the Spyderco's flat
within a few hours.

+1 They are a to lap. I think I'm going to buy a d8xx just to lap them..........

Speaking of which, anyone want something ~$20 from craftsmanstudio? I can't get it to $100.

This is prolly a bit late to help out the OP, but this guy reports that it only took him about an hour to lap his spyderco

I'm ordering a spyderco and I'm gonna try the method he outlines. I'm not really interested in spending hours upon hours getting a hone lapped.

I read that post as I was furiously lapping away at mine with a D8XX, btw, it still takes forever.

First, he is lapping a fine, so not the untra hard UF. Second, different stones have different straightnesses from the factory. All are guaranteed to be within .002", but thats a lot variation when it takes forever to lap these suckers. Third, if you read carefully, he only laps about 3/4 of the stone, he leaves the ends a little submerged than the middle. Finally, I think he only lapped one side. Thus...I think his method does not calculate the true costs in lapping those tough sons of .

HOWEVER, once they are lapped, they work wonderfully. In fact, I would say that once lapped, the value increases to maybe 2x the retail. Except the 4k grit one, that one took maybe an hour, probably less. That one was really easy. In comparison.

Yeah, the possible difference in the material occurred to me. I guess I'll find out if it's as effective on a UF.

Actually, he says that he only left 1/8 of an inch at an end unlapped, not 1/4 of the stone.

I'm hoping that using a 80 grit abrasive will help expedite the process. The commonly used plates may be diamond, but they're 325 grit, I think.

D8XX is 120 grit or so. Btw, my UF took less than an hour to lap one side completely smooth, while the fine took more than 4for one side. Needless to say, the UF was a lot straighter, so YM is going to vary. They're great hones, but a to lap. I wanted to pay a machine shop halfway through or pay some college kid to do it for me. Oh my god it was aweful.

Actually, now that I think about it, sandpaper might be best. No chance of damaging a $70 diamond hone. May be slower, but...safer. Definitely safer.
