Jig to help you line up your chisel or planer knife with the correct angle for sharpening | Download free 3D printable STL models
I've designed a 3D printable sharpening angle jig for your chisel and planer knife. Works with those cheap triangle shaped blade holders you can find almost anywhere for cheap. Check it out if you're got a 3D printer.
As someone that has never sharpened a chisel, I have no clue how this thing would be used from the description or pictures. Not that you need to pander to me, but if interested in a broader audience, I feel like a video would be very helpful here.
There is a picture on the site showing how to use but you'd have to know what the honing guide is too for that to make sense. This really is only good for people who want to sharpen a chisel.
Not sure this type of thing is useful to a broader audience. It is specifically for those that own chisels and/or planes to help with setting things up for sharpening. Anyone in that space who owns a honing guide and set of sharping stones will find it fairly obvious how this functions from the given details and pictures. For anyone that wants to sharpen a chisel or plane blade and does not yet know how there are a lot of guides out there that will go over those details where this device is only one small optional part of the picture - at which point the intent for this device becomes more obvious.
