I was talking with Rob Keeble about rasps and rifflers and had said I'd try to dig up some of the ones I have for comparison and figured I'd just post it here as the site will resize the pictures for me
These are most of the nicer rasps and rifflers I've collected. The ruler is a 6" ruler for scale.
First up is (from top-bottom) some Corradi needle files I got from Lee Valley, some Gramercy (TFWW) hand stitched Rifflers (pakistan), and some lee valley detailed rifflers.
Next is an Aurio curved #8, a Gramercy (TFWW) hand stitched half round (#10 I believe), and a couple of medium iwasaki "mill tooth" files.
Finally a Shinto saw rasp and a Grobet 4 in hand (has a fine and a coarse side).
Cuts are all in the same cherry the spoon I recently made came out of. Please forgive the bad hand writing.
Shinto saw rasp cut.
Coarse and fine cuts from the Grobet 4 in hand.
The Aurio (which is fairly coarse)
The gramercy half round and the Corradi needle file
Finally the gramercy riffler and the iwasaki medium.
I didn't test the lee valley detailed rifflers, they're somewhere around 220 - 320 sandpaper (nominally 69tpi but they seem to cut even finer), the finish from them is polished but they don't really remove any meaningful amounts of material. A bit finer than the Corradi needle files.
