Ive been a carpenter for about 13 years and its been some combination of Spyderco endura or delica, Emerson cqc-7 I carried for about 3-4 years straight, a regular Griptilian sees some carry time as did a CRKT m16 zytel till it folded up on my finger. My main workhorse knives seem to always come back to a Delica/Endura. Especially the new FFG Endura, I cant seem to let anything else in my pocket for work since I got it. Too light, flat, tough, and sharp.
Truth be told my heaviest use of my EDC knife was during the time I was doing punchout work for a builder. I had to do so many different types of jobs in a day that I couldnt work out of a regular set of belt tool bags, so for the larger portion of my day I didnt wear any. Hence no razor knife. During that time my edc blade was called on to do everything from open caulk tubes to scrape crap off door thresholds to cutting the black drainage pipe that invariably gets left sticking out of each yard. The emerson really excelled for me in that roll. Especially the ease of sharpening which seemed to be every few days.
I learned how to sharpen REAL good during that period, Lol. Nowadays I do mostly carpentry, so I work out of a apron and my EDC doesnt get "alot" of use. Always have the replacable razor knife in my bags, as well as a beater mora something or other that just gets absolutely ABUSED by everybody. Ill have to post a pic of that one some time you guys would get a kick out of it. Its the reason everytime I read someone bragging on how tough thier knife is I have to giggle a bit, when theres not a scratch on it.
Funny thing in closing. I have never figured out why, in MY industry, Im always the only guy on the jobsite with a knife in my pocket , isnt that crazy! The other guys are always askin me to borrow a knife to, hence the cheap replacable mora. After the last guy I caught cutting playing card cabinet shims against a brick wall with one of my razor sharp freshly honed edges, I dont loan out my edc anymore. You'd think a bunch of grown men carpenters would be smart enough to have some type of knife on them all the time. Were not children after all......
