for practicality what is your personal preferred shape for a small and or big knife? and why? how dose it work better for you than another shape? whats that shapes purpose?
i see a lot of "survival" knives in shapes that look uselessly trendy. "tacticool" as my bf puts it. which is fine for a knife collector that hangs them on a wall but of little use to a bushcrfter. unfortunately i think many beginners go for these knives thinking they are bad@ss and actually plane on relying on them in the field.
when i watch knife reviews i often wonder why that person chose the knife shape that he did. if its actually the best for his intended tasks or if he just liked the way it looked. its not usually discussed. this left me wondering how much thought most people really put into it. i mean do most people analyze how a knifes shape will effect its performance? i would think so but when i look on youtube or knife forums it dosnt seem like it.
we have been looking to get another big knife (something we can chop and baton with) and one of the knives we were considering was the SP10 marine knife.

now i dont think it would be a bad knife, however we decided against it because of the way the tip clips like that. reasons being...
1. it would take weight off the front in comparison to one with a flat spine. this is bad for us cause it reduces chopping power.
2. the tip is more fragile then one thats a bit more blunt. not that i think its likely to brake but we will be batonning with it and it just gives a better piece of mind to have one thats as sturdy as it can be.
3. the angle of the tip looks like it might be a bit awkward to baton on wile trying to keep the blade straight. unless we were batonning at the very end of the tip but as i said in #2 that looks like a weak spot.
i believe the tip would be good at delicate work compared to a more blunt one but thats not what we want so we are going with something else.
