I wanted to get y'alls opinion on this file. I would like to start adding checkering, or jimping lines (not sure what you call them), along a one inch section of the spine. I thought about trying it with a triangle file, and space them on my own, but realize the best looking lines will probably come with the proper tool. Is this what I need? This one is 20lpi. Thanks guys.grobet.jpg
 
Use that file to scribe lines at the correct spacing. Then use a knife file to cut the grooves. If you try to cut the lines with that file you will ruin it.

As long as the steel is annealed, the checkering file will work fine.
Hardened steel will dull the file, but it might take some time before it's unuseable.
 
Depends on the steel. I ruined one jimping annealed M390 by the 3rd knife. I got about 10 knives with annealed S35VN. Also, you will, IMHO, get cleaner grooves by using the knife file to make the grooves.

I use a checkering file just like that for my jimping. I always cut the jimping BEFORE heat treat, and I've gotten dozens of cuts with mine and it's still going strong. The nice thing is that you have two sides, so if one dulls, you still have another... ;)

I just make sure to knock the chips/dust out every now and then.
 
I use a Grobet checkering file just like the one shown above. I do not use it freehand though. I put a guide on the blade to keep the file square and the lines perpendicular to the spine. If you introduce any twist during a stroke with these files, you will break off teeth and substantially reduce the cleanliness of the lines.

Good deal. Thanks for helping me make sure I'm on the right track, right train. Most all of my knives are the simple carbon or low alloy tool steel, and I'll cut the jimping while annealed.
