I was going through some gear and came across a tool that I won’t leave shore without… I use a battery operated Dremel 7700 tool to sharpen my hooks.
I use a 952 bit, which is sort of a cone shaped sharpening stone. This allows me to sharpen hooks quickly and ultra sharp because I can get to all sides of the hook. I like to sharpen down two sides of the hook to get a sharp edge on the inside or barb side. I’ll then touch up a third side at the point real quickly so the point is needle sharp..It takes a little while to get the hang of it, and with softer hooks you’ll actually want to be careful to not grind off too much
Batteries last pretty long but you could get a back up to bring out (I haven’t needed one yet). I usually charge mine every 2 days.
Just thought I’d share this… I see a lot of rusty files and dull hooks come into my boat. I am obsessive when it comes to sharp hooks!
