If you like keeping hooks and knives sharp - and sharp hooks are critical for sharp hookups - the single best machine you can own is a belt sander. A simple 1x30 can be had from Cambodian Tire or Princess Auto relatively cheaply.
You order a couple of Trizact belts from Lee Valley, one 45 micron and one 6 micron. The 45 micron belt will give you the rough shape and a wicked filleting edge on any knife in seconds.
The 6 micron you use to polish the point of the hook at a shallow angle. Once you get the hang of this, you can make hooks sharp enough that you won't really feel them go through your finger - it's like a hypodermic needle. It's not that the tip is super fine so it would bend or break, it's that the surfaces are polished to such a mirror finish that they intersect with each other smoothly on a microscopic level. They push through tissue like a tiny scalpel.
This can be achieved a lot of different ways but the belt sander allows you to do it in a few seconds. Just don't use too much pressure! You will overheat the fine metal tip and wreck it.
Maybe this coming week I will do an instructional video if there is interest.
