Maybe in time, the cost will be less for bonded CBN. Either way, it's been on my radar for a while. Kinda hard to justify right now though, with all the stones I have. When they begin wearing out, it will be time to upgrade.

Does anyone know where the Spyderco 400 mesh would rank on this chart? I'm guessing ANSI but if anyone knows I'm curious.

Hi BBTurbodad - I’d use the ASTM (American Society for Testing and Materials) Sieve column as a reference. 400 mesh sieved particles will roughly be around the 37 μm range.

I quite like the Venev system of just specifying an upper and lower micron range for the abrasive particles in a given stone.

Looking at scanning electron microscope images of abrasive particles in pastes, emulsions and stones usually show a fairly wide range of sizes.

That’s exciting news about the new double sided CBN stone - I’ll be looking forward to trying it out. I love the CBN Doublestuff pocket stone and highly recommend it. It’s also very useful for freehanding serrations, particularly the scallops between the tight ‘spikes’.

Sal, we haven’t heard much lately about the 701 Profile stone set? I’d still be very keen for another run. :)

Hi Cambertree,

We got new quotes on the 701 Profiles and we felt they were too expensive t make them and be successful.

Sorry

Thanks for the detailed reply Cambertree!

I have the Venev stones and use a Sharpie to write the FEPA number on the face of each side of the stone for easy identification and completely forgot that the other "edge" of the stones have the micron values so at first I was thinking what the hell is he talking about. :D

No worries, BBTurbodad. :)

Yeah, when I first got a couple of the Venev benchstones, with their Russian instruction sheets, I was confused as to what those numbers like '20/14', '7/5', '3/2' and '1/0' engraved into the sides meant. After consulting Google, I realised it's a pretty neat system.

Hey Sal,

Oh, that is disappointing, but thank you for following up on the previous discussions requesting another run of the Profiles. :)

I don't think there's any similar shaped sharpening stones out there.

I blame JDSpydo for getting me interested in these unique pieces of sharpening kit. :D :p

Ah well, I'm sure I'll be able to find some second hand ones eventually. It speaks well of their usefulness, that most people who own a set seem to hang on to them.

Hey Cambertree,

The "ProFiles" were a predecessor to the Golden Stone. The Golden Stone was designed in '78 when the Sharpmaker was designed but the technology wasn't there to build it. We held on to the concept for years until we finally made the Duckfoot and then the Golden Stone.

Thanks for the background history Sal, it's appreciated as always. :)

I love hearing about those concepts that got filed away in the 'ideas bank' until technology caught up years later, and allowed them to become reality. :cool:

It would be great to eventually see resin bonded CBN stones in various shapes, like the cats eye Gauntlet stones, Sharpmaker rods and ceramic file set.

Yeah I was thinking I might have to check out the Goldenstone now. I've been interested for a while, but the 20 dps only angle, had me holding out for the 15 dps base to be released.

Now, about that long awaited Spyderco nosehair trimmer...:D :p :)

I've use a Sharpmaker for more than 25 years. I upgraded to the latest model in the past couple of years because the Tri-Angle rods can be used at different angles now. I've got the diamond, brown and white Tri-Angle rods.

Here are a few things I've picked up over the years. I can't claim any are an original idea.

I used to use a kitchen cleanser like Ajax to clean the brown and white Tri-Angle rods, but use a pink pencil eraser, now. It seems to be faster and less messy. No pencil eraser on the diamond Tri-Angles, just water, as recommended.

On a new knife and especially on any brand other than Spyderco I'll use a Sharpie on the edge grind to figure out where the Tri-Angles are touching the edge then lean the blade more or less to remove the Sharpie ink to match the grind o' the edge. (They don't call it a "Sharpie" for nothing.) :rolleyes: Rubbing alcohol or acetone, (nail polish remover,) and a cotton swab will remove the left-over Sharpie ink from the blade.

When I get down to the white Tri-Angles I'll drag the flat part of my fingernail across the edge at 90 degrees to the edge, pulling my nail away from the edge. (The opposite way you'd shave something.) In doing this I can see if the edge is rolled; it's usually rolled to one side or the other. You can feel the rolled edge shaving your fingernail while the opposite side has less/no friction. Then, I'll lightly use the white Tri-Angle to "roll" the edge back straight. When I get to that point, I'm done! You can pull the blade across a dry piece of leather and get the same effect. Just like a strop.

A friend brought me a knife with a Tanto blade that had been "sharpened" by a buddy using something abrasive and powered by electricity. (If I had to guess I'd have thought it was a wood-fired grinding wheel.) His Tanto blade looked like a cross between a clip point and a khukuri blade. I placed an aluminum oxide stone on a Tri-Angle rod that was placed in the Sharpmaker base to re-profile the edge back to 20 degrees. I used the Tri-Angles to finish the job, turning it back into a sharp Tanto blade.

You can use the radiused (curved) sides of the Golden Stone to touch up the large scallops of a SpyderEdge blade; they're the same radius. Coincidence? Probably not. ;)

No problem. He's been an active member here for a while, a custom knife maker, makes YouTube videos, and is quite knowledgeable about steels and heat treatments.

OK, I'm still not finding a website. I'm guessing he has an on-line shop?
