I’ve gone and got myself a Stanley #81 and some standard scraper. I stoned them, turned a hook and managed to get them making some decent shaving. The problem i have now is that i need to resharpend. I read somewhere that i should file past the hook, restone, then make new hooks. I also remember reading where somebody pushed the hook back, stoned, then rebent the hook. My two lines of thinking are that this could either work harden the material, good, or fatigue the material, bad.

Wondering what your guys opinion is and if you had any tips.
Thanks!

You can recycle the hook a few times before you need to completely resharpen. Once you refile the scraper any work hardening or fatigue is gone.

Yes, you should be able to skip the jointing/stoning and just burnish the edges flat and then turn the hooks a few times on a card scraper.

Not sure what you mean by “standard” scraper but the #81 is prepared differently than a plane card scraper. On the 81, you only have a hook on one side of each end and you want to hone at an angle rather than with square edges. You should still be able to refresh the hook with just a burnisher between honings though.

FWIW I sharpen the iron on my #80 with a 45 degree bevel and create a burr on the flat side of the iron, away from that bevel.

Here's a pretty good article on it.

Sorry fellas I wasn’t too clear. I sharpened the blade on my #81 to 45deg (thanks for the article chris, I’m going to try 30deg next time), then I used a wet stone, then I did a burr to around 10deg ish.
I also bought some card scrapers, wet stoned them at 90deg and turned a hook.

I’m not really sure what you guys mean by recycle the hook?
Do you mean push it back flat then turn it again, or do you mean just reburnish at the same angle as the original hook?
Thanks for the help gents!

Nakmuay,

StumpyNubs produced a video in 2012 that may be worth a view. He discusses the cabinet scraper’s use and sharpening. He also covers scraper holders like the Stanley #81. The relevant discussion runs from to 1:05 to 16:08.

He presented cabinet scraper sharpening again in May 2016…

There are additional YouTube videos where others demonstrate their methods for sharpening the cabinet scraper.

Personally, I use my burnishing rod to push it back flat and then re-hook the burr. I think many simply run the burnishing tool back at the hook angle. I just work it with the rod until I can no longer roll a consistent, acceptable burr. Then I know it’s time to joint the edge and start fresh.
