Chisel sharpening


Recommended Posts

Does anyone have any good tips for sharpening a chisel? Mine has recently grown dull from excursions to the local quarry for quartz. Any tips are appreciated!

Get yourself a grinding wheel or go to someone who has one.

If you never used a grinding wheel be very careful and get your neighbor to show you. Sorry I work in Design Technology collage in the UK they drum so much health and safety into use I can't stop my self saying this. Cheers Bobby

I would be extremely careful using a grinding wheel and not just for the safety aspect. If done improperly a wheel can cause you to overheat the blade.This can cause the blade to dull prematurley and basically ruin the blade. Personally, I use a good file to sharpen my chisels, whether for rock or woodworking

He should be able to help he sharpens axe blades and such quite often. What type of file do you use? This would probably be a lot easier for the future.

Thanks for the warning, safety is always good to have on your mind. My neighbor is experienced in using it so it will be fine if I end up going over there to sharpen it.

Grinding wheels are great. Once you get practiced on it, you'll be able to whip it out in minutes and be on your way back to the quarrry.

 Like UtahFossilHunter says, just get yourself a grinding wheel and sharpen it,  Only take a couple of minutes and your done.  Wear some safety glasses.

A file is a cheaper option and works fine.

You should use a full sized "fine" file to sharpen a chisel. Also try to keep a similar angle on the tip to what is there already.

I'm in the grinder camp. The thought of sharpening a hardened chisel with a file makes me cringe. It is very easy to touch up a chisel with a grinder without ruining the heat treatment. All you need to do is dunk the tip in a bucket of water once for every 20 seconds or so of grinding. This will keep the hardened edge cold enough to stay happy. I do this all the time when I'm doing finish work on treated and tempered knives. I've never ruined a heat treat doing this.

While grinding, keep periodically quenching the tip in water. Overheating the grind area will make the tool lose it's "temper" or hardness. If that happens the chisel will dull fast.

I use the grinder wheel on a stationary motor. You can use an angle grinder with a metal grinding wheel as a cheaper solution.

Always wear glasses or use a shield, quench in water as you go and take your time.

Remember to always grind off the splayed material on the striking surface as that is where pieces will fly of the chisel when in the field.

Personally, I like to take old tools and forge them into knives... but I have been accused (rather unfairly in my opinion) of being a bit odd.I have an old digging bar that is just begging to turn into a claymore!
