Just some general comments (from a guy who had bleeding fingers several times, just too lazy to grab the right tool or to cover sharp stuff).
Use a vice to clamp bike part or tool. This works in a safe way. Complete wheel of frame give plenty leverage. Also, it reduces the risk of slipping (tool out of BB cup / cassette lock ring, etc).
Allen keys are available in different length. Longer tools offer more leverage. However, most people use short keys.
Long time ago, Shimano supplied a piece of steel tube with a 6 mm Allen key for their handlebar stem, because a higher tightening (and loosening) torque was required. This trick (and tube) can basically be used for any Allen key and bike part. Just use a longer allen key (or any other tool), or make it longer with a decent piece of steel tube. It also keeps your fingers away from e.g. chain rings when working on cranks, chain rings, etc.
Use a decent pedal wrench instead of a normal (15mm) open wrench / spanner.
It fits on all pedals with flats for wrenches (normal spanners are too wide for many pedals), gives more leverage because of the length, keeps your hands away from the rings. Don't use the cheapest bike tools here, because the steel is really soft. Cheap tools ruined after 1st attempt. Campag, Shimano, Sugino, Park, etc. is all okay. Forget about no-name Taiwan/China/India sh*t.
Multi tools for emergencies only.
Use a pipe cutter instead of a saw for pipes (steerer, bars, seat post, etc, as long it's no carbon fibre)
