This thread is kinda ironic... A year or so ago was going through my knife collection (have quite a few) and notice my little limited edition penknife, a Schrade Cope USA #C194 Delrin Copenhagen Snuff Linerlock Slimline Trapper Knife (single-blade) was showing signs of corrosion and I don't remember ever carrying it... Anyhow I decided to carry it a while to wear it off... Have always carried a little keychain knife for decades, but it has been a long time, probably since a kid I carried pocket knife, but remember my grandfather always carried a penknife, which I actually have... Through the years have carried the Buck 110, the Bucklite, and the bigger folding hunter, (have had a few Buck folders) but they always seemed to big for everyday carry, and sometimes scared people when I brought them out so eventually evolved to a little keychain knife… Bummer when you don't have your keys on ya though...8^) but always have a hunting knife in both vehicles just in case...
So after carrying the little Schrade a while I realize I really, really liked it and started carrying it for everyday "all day"... It is very light and I didn't notice I had it on me along with a Bic lighter... My grandpa was a smart ole man and now realized why he carried one... Then I lost it and was bummed, although I eventually found it under the seat of my car... Afterwards, since it was a limited edition decided to put it back in my collection and find an alternative... After a little internet research, the first one I bought months ago was the Schrade Old Timer "Pal" Model 120T (single-blade)... Being a Schrade that looked similar in pictures to another Schrade I figured they'd be the same size and feel, but they are not... I put them on digital scales, and the Old Timer "Pal" is 424.6 grains and the limited edition Slimline Trapper Knife is 391.4 grains... You wouldn't think that little bit of weight would matter but it did along with the sharper scale corners... Just doesn't have the same feel in my pocket...
I really wanted another traditional style penknife and the next I bought was a Buck Model 375 "Deuce" (2-blade): 295.4 grains which is a little smaller and has two blades, but it's actually too small...
Next I bought the Buck Model 379 "Solo" (single-blade) 348.2 grains... Although I like the limited edition Slimline better, it's about perfect and easily available and won’t scare people when ya pull it out...
It's not for hunting but rather everyday "all day" carry and if I have any pants on with a pocket my little light weight Buck Solo penknife is in it all the time... They are affordable and readily available if I loose it, I'll just go buy another... And, if I had too, I could gut and skin a buck (pun intended...8^)) with it too...8^)
