A thought on quality blades: I don't like to see tools misused. Include guns, cars, wrenches, knives, screwdrivers, and all the helpers an opposable thumb could need. Sometimes a situation can be solved by sacrificing a tool. Sometimes a tool is lost. If you have a knife that is good enough, and not expensive, you will not agonize over solving your problem at the cost of the knife, nor agonize over a lost knife. I keep some survival gear in the detached garage. I keep some in each of the vehicles. I don't have the coin to tie up hundreds of dollars for each place I want a knife available.
Another thought: the ubiquitous knife of the Bering Sea fisherman is a disposable fixed blade Victrinox steak knife. Its serrated blade will cut bait, net, or shot lines. It costs only a couple of dollars (the sheathes cost $10, more than the knives). Most guys working on deck will carry two or more; if one is dropped or inaccessible, there is another one on hand. When they get dull, they get thrown away. Someone so inclined can put an excellent edge on one (I used to use one for cutting patterns and custom gaskets.) The mostest wonderfullest wunder blade does you no good if it is lost, or if you are afraid to take it where it will get dirty, rusted, and mistreated. Good enough is often the best solution.
