I carry a combo of folder and multitool. The performance of the multitool blades is adequate for many purposes but itīs no match for a knife. The folder is easier to clean when has only one blade or two. I only use folders that can be operated with one hand.
I prefer plain edge. I donīt have to cut a lot of rope and itīs easier to sharpen.
For most occassions I carry a Buck crosslock a Leatherman Micra and a Gerber Multiplier. The crosslock has a gutting hook that can be used for cutting seat belts clothing and small ropes. I chose the Gerber Multiplier because it can be opened with one hand.
For motorcycling I have a Spyderco folder and a Leatherman Wave. I selected the spyderco because it has a robust clip and not much bulk for its size. The Wave has good tools and onehanded opening is not important. I like to have scissors with me.
I have a small fixed blade in my wallet. This knife is handmade. I carry it for jobs that would damage folders. It can even cut metal and stay sharp.
For hunting and fishing I add a 4" fixed blade with a drop point. The fixed blade is robust and easiely cleaned. I prefer the the drop point because I find it easier to use for dressing the fish and game. The knife is handmade because I could find one that satisfied my needs.
