I got nothing against the small vic Penknife, but I do enjoy the Spey.
It is a good shape, and maybe you are less likely to damage the tip?
I generally use it for the same things I use the small penknife on a Vic for - the nasty tasks I do not wish to risk the main blade on - either due to potential for damage, or just gunkiness.
I'm also a big believer that you only need to use a knife as big as you need to use, and big pointy blades are for blokes with either.
a. something to compensate for.
b. a fetish for injuries, or
c. a higher pain tolerance than me.
