I have a couple
the one that looks like a marbles knife is a regular user , the straight one is gunna get redone , needs working on , Ill get around to it one day if I dont off load it first
they arent choppers , but then I dont want choppers in a knife this small , just game dressing knife .
they are good blades , take a great edge and really hold it well , I like using a knfe that is way older than me too , like keepin history alive sorta
In the early 90's knowing Solingen steel reputation I bought in Army & Navy Surplus store knife on the right "Edge Mark" Solingen Germany with carbon steel "461" blade that seems to stain easy.
It's a great fixed blade, very comfortable in hand, extremely light weight.
But it has one major problem, cheap thin long bendable finger guard.
When it's straight it hits cutting board surface so needs to be bended, but because it bends so easy by hand I'm afraid eventually it will break off.
Also, being made from cheap brass it gets green oxidation very easy even more so than my other knives from China, India, Pakistan that also have brass bolsters.
That is why I don't use it much, once a year I have to clean off green oxidation gunk it spreads to leather sheathe and on clothe.
That oxidation occurs even when storing it in dry shoe box, it gets worse from blood, sweat or water.
My second knife was a gift, it's classic 3-blade slip joint "Carl Schlieper" Hammered Forged Solingen Germany Carbon steel "425Y" with silver shield and yellow plastic handle with squared silver bolsters, American version of this knife was called "Jim Bowie".
Being yellow handle non-locking blades classic looking gentlemen's pocket folder it's very "sheeple" friendly especially when using small pen or sheep's foot blades.
I put 15 DPS convex edge on all 3 blades now it's a wicked slicer, but it looks like it has soft 54-55HRC steel that gets dings in it.
But 3 major issues that makes it less than friendly/ heavy duty user for me it also applies to all slip joints even ones with stainless steel.
1. Non locking, need two hands to open blades big minus in my opinion.
2. Carbon blades that get finger print stains every time I pull it open.
3. While slim handle makes it easy to carry in pocket, it isn't very comfortable in hand for tight grip for heavy use, due to the fact that remaining two closed blade spines dig into my finger when tightly wrapped around slim handle. The only comfortable grip is loose with index and thumb fingers, which limits the use for this knife to very light duty.
Also, that is why I stopped using my SAK and switched to Leatherman Wave.
For all those reasons I prefer modern knives, better materials, better ergonomics, better locking mechanisms, easier maintenance.
