Thread: BIG chip in russian ebay blade

I've got a nice set of 7 russian blades I got mostly from ebay( one from sham) that I got very cheaply to practice my honing skills on( the sham blade of course is perfect edge). Five have seriously dull but passable edges. Two have pretty serious chips in them

I put one on my DMT 325 to get the minor( but plentiful) rough edges out and it worked great til I discovered this half moon shaped divot in the center. How does one take the edge down to the lowest commmon flat surface so I can start over with a new bevel?

thanks

Two methods:

1. Just keep honing until the rest of the edge is ground back to the bottom of the divot;

2. "Breadknife" the blade -- check the Wiki for instructions.

Freehand hone the edge at a low angle. It is easier to restart the bevel than with "breadknifing"

The easiest is to buy a razor without big chunks of steel missing. Of course, if your time is worth next to nothing the total cost may still be better than simply cutting your losses as early as possible.

Or you could look to the positive: if you hone that out properly your muscle memory will have well and truly kicked in!

of course, but the six others I bought only need minor hone work. and I didn't even see the chip til it was under the scope. the practice is worth much either way

exactly what I was thinking too.

How powerful is your scope. I'm asking because if I can't see a chip with the naked eye, then it's not really a big chip. Something that i can see without a scope, that's less than say 1mm wide or deep, can usually be taken out with some pressure circles on a 1k. If you want to drop it down, use your 1k with a good slurry.

If I'm seeing chips at 10x magnification....I just hone like normal.....start at the 1k.

good point,I didn't know that. My scope is very powerful( 60-100x mag) and I can't see it at all with the eye even up close.That's why this forum is so good,being able to benefit from you guys's experience.It just looks pretty craggy at that mag.

Anyway I just breadknifed it on my DMT 325 and it came out very quicky. I had reset the bevel yesterday and it looked great except for that chip. Now it's very even and I can start over. This kind of practice is what I got these blades for. thanks

Noooooooooooooooooooooooooooooooo
If the chip is not even visible with the naked eye, breadknifing it on a DMT is like killing a mosquito with a hammer.
Doing a couple of passes on the 1K works just fine.
