Anyone have moderate to longer experience with tubeless mountain bike tires? Thinking I may eventually switch from tube type wheels. What have you learned both good and not-so-good?

Thinning Damascus (or fake Damascus) is something I've wondered about as I've never done it. But I have a professional chef where I sharpen his 8 knives. Probably 6 of them (Shun/Wustoff) have been sharpened back so far over the last 2-3 decades that the edges are really thick at this point...

Back with my machine/mold shop days we used diamond wheels for that. No manual work.

KKF is overwhelming on the subject of knives, but I started remembering all the "other" things I've sharpened recently. 1. Spatula end (sides too, for some users on the grill) 2. Carving/Serving fork tang ends 3. Screwdriver blade end 4. Potato peeler (really makes it peel easy compared to...

When I use my low speed horizontal lap on knives with just a super-dull rounded edge, I move from 120 grit to 220 aluminum oxide and then 360 & 600 grit diamond. I put an 8" blade in far better than "new Wustoff" condition in 10-12 minutes maximum. More time is often needed in profileing a...

But there are still a lot of reasons that a powered sharpeners will cause "headaches." 1. Personal knowledge/touch is still required. 2. Failure to sharpen "right to the tip" & sometimes to the heel if it has a finger guard. 3. Not maintaining even pressure and speed which tends often to...

Hard abrasives will immediately destroy the shine on the side of a polished blade. Most knife owners don't want to do that.

I routinely use crocus cloth (iron oxide powder on clock backing) on my customer's knives to remove spots and have never seen them leave a scratch. I only see littles stains or spots, so I've never tried a truly bad rusted knife which would be a horrible thing to resurrect.

It it better than using crocus cloth?

VERY low viscosity hydrocarbons according to Wikipedia's sources.

Anyone use WD-40 to loosen up stone/oil residue in the pores?

Got one to beat them all, and I guarantee you will agree! 'Sharpening' on a concrete curb is definitely for losers.

What in the heck sort of damage existed that you have to take 3mm (1/4") off a blade??? Only reason I've ever had to take 3-4 mm off is when someone drops a knife on a counter edge or floor.

I sharpen Shun's routinely. The people who seem to buy them use them as cleavers as far as I see &/or drop them on the floor and take 1/8"-1/4" deep chips out. I try to suggest never "clicking" or "thumping" a Shun to avoid chipping. Some people listen and some don't. I personally have a...

Using a fingernail sideways pressure on a tip of a real fine edge will bend it when you look at it under a microscope.

With 60 years of knife sharpening along with my machine shop work, I've come to a couple conclusions on metal edges. I have no way of proving if anything I do is "right" but it seems to work OK for my customers. The few that are really touchy seem to appreciate my work, though I don't work on...

I never did have twist shifters until I got a Diamondback mountain bike. What I found is that I didn't need to work two separate Shimano levers to go through the range of sprockets. To go up on sprocket size often takes 2 pushes on the "large lever", which I see as an annoyance. Bought a...

OK, anyone routinely using any of the Hasegawa, Asahi or Tenryo softer polymer boards and how has it gone with them. Korin.com has a large range of them. They seem to be either soft Polyethylene (PE) or Polyvinyl acetate (PVA). None of the cutlery shops around me sell anything but their...

"Just be happy they aren't asking you to sharpen their forks." Well, I actually have sharpened tangs on a few carving fork sets. The kids probably used them somehow on concrete was all I could figure!

First bike was a used Columbia which I cleaned, oiled & painted up with flames on the fender tips when I was about 7 & it served thru high school. No one had "10 speeds" in those days in St. Helens, Oregon. First thing I did no day one in San Luis Obispo @ Cal Poly was to buy a Schwin 10 speed...
