I carry a couple of different folding pocket knives for day-to-day use. But, my uncle was an avid knife collector and was also a sailor, and when he passed away, I what was left of his collection. There are some that I keep because of sentiment, but most are useful.
These are all of the "good ones" by my estimation. I determine this by maker's mark, quality of steel, quality of hilt, and also sentiment.
Classic KaBar. This was a gift to my uncle from a boss we had, at one time, both had. He got it at an estate sale, and its a very good knife. I love the patina on it.
If anyone knows hunting knives, they should recognize the name Morseth. I am lucky enough to have two of S. Morseth's knives. Model 83 M3-3
Notice the ingenuous locking mechanism in the sheath. Love this.
#2 Moresth. Not as useful as the first one, for me. The first is a perfect skinning knife for elk. Model 84 M8-25 Gold Dot version. It means its a collector's knife, and I won't ever attempt to use it.
Solingen Bowie Knife Model 447. Huge Bowie Knife. I have seen this knife used to pop/break the breastbone of elk. No saw necessary. Hugely strong steel. Excellent knife, for its purpose. Completely impractical for any other real use, other than to scare someone.
Nameless Kukri. Probably picked up in the Mediterranean Sea, probably in Turkey. While it is not a typical Kukri, the grip is of lower quality, but the steel is excellent. No maker's mark.
I have fine assortment of folders, throwers, and a pretty neat but cheap wrist knife, as well. However, these are the fixed bladed knives of value. Will trade many of them for good lenses, however....
