We’re happy to announce that we now have Diamond Bars from Ken Schwartz! These specially formulated diamond bars are packed full of diamond abrasive, making them very fast, and very consistent. They also come in a wide range of grits – from 80 micron down to 0.10 micron! So if you’re removing rust from a blade, repairing chips, profiling or reprofiling, sharpening, or polishing the blade, these bars are essential.

Ken Schwartz Demonstrates the New Diamond Bars

Hi, my name is Ken Schwartz of Precise Sharpening, and today I’m going to be demonstrating a new product. These are called diamond bars, and this particular bar is a four micron bar. That’s about a 4,000 grit bar.

Now I have these bars right now going from as coarse as 80 microns down to as fine as 1 micron, which is a 16,000 grit, and hope to be getting some further grits that are even finer. So what I’m going to do with this particular knife, it’s a powdered steel knife, it’s made by a company called Blazen or Ryusen, and you’ll see that in this particular knife it’s gone in and out of the side a lot, and I don’t know if the camera will catch it quite right, but there are a number of longitudinal scratches in the blade that I’m going to be buffing out to a finer finish using the four micron wheel. This is a cotton buffing wheel, it’s an 8 inch wheel, and so I’m going to turn it on, and I’m going to show you first how to load the wheel.

So I’ll flip it on and off briefly, and put the bar into the wheel. Okay, so here we go, and rather than doing it at full speed, I do it when the wheel starts up and slows down. So here we go, and just like that, do that once or twice, okay, almost like a brake.

And so that’s what you need to put it on the wheel, and now I’m going to demonstrate working on these scratches. Now these wheels generate a lot of friction, and you have to be extremely careful not to get the top spine right into the wheel, or it’ll catch and very forcefully throw the knife. And now I’m going to do the top part of the knife, being very careful not to catch the edge.

So now let’s take a look at this and see what we have. These diamond bars are named because they do have diamond in the bars, along with a few other extra ingredients. And we can take a look at it.

There’s a slight bit of wax that gets on there, and so you take the wax or buffing compound, and now when we look at it, we see a very uniform, shiny finish. Very quick. Thank you very much, I appreciate your time watching it.
