Nice...Unique look for sure.
I posted in another thread, asking opinions on the Best way to add Thumb Ramp & perhaps Spine Jimping to an existing knife that is without.
Would you say diamond files for this, as well?
...I don't have this type of file or a dremel tool currently.
BTB
For anything requiring precision and/or uniformity, I'd strongly recommend against using a dremel. I occasionally use a dremel on knife projects, but only simple stuff, and tasks with room for error.
For anything requiring precision and/or uniformity (like jimping) I'd recommend diamond files.
The first difficult step can be acquiring the right files- the right shapes, the right grit(s), and the right quality. Below is a pic of all my diamond files (not counting doubles). Some were inexpensive, but still of good quality. I've had them for many years and have used them for countless tasks, not just knife stuff. I've purchased other sets, some more expensive, but sent them back because the diamond surfaces were unevenly rough, rendering them useless for all but the roughest work (which I didn't need).
The two sets in my pic I purchased from Amazon. The large set are all flat files, but there are six different grits. The small set are the smallest diamond needle files I could find. They're great, particularly for precision work, and come in a variety of shapes, but they only come in one grit, which I would compare to an extra-coarse DMT diamond hone. That may sound aggressive, but I find them to be a good universal grit. The flat file set is product # 74330DF, and the needle file set is #FIL-974.00 (both on Amazon). I checked and they're both still being sold.
The other three round/rat tail files I purchased from Mcmaster-carr.
As with any files, use light pressure. Let the file do the work. Pressing hard won't get the work done faster, it will only wear out the file faster.
