PetahW....looks to these old eyes that you're a pretty handy feller.
Like all of us that have dabbled in this sport / hobby for many years, I too have tried my hand at a more'n just a few blades.
Some were good, actually very practical, but some where not much of anything....wasted time and material, but the guys loved them and they made decent gifts or Trade Blanket material.
I learned years ago, following many mistakes, that my own "personal" preferred blade length, for an actual work knife, should never exceed 5" with 4.75" being just about perfect for me.
I own a lot of pocket knives too, not that I collect them or anything like that, it's just that for years the Kids and Grandkids all thought that I was somehow in need of a good pocket knife, so for Birthdays and Christmas you could just-about bet someone was going to throw in a knife of some kind. Plus, when you've had as many Birthdays and Christmases as I have....well, you get the picture.
Very nice Knife collection! I love a good knife...
Respectfully, Russ...
