First: Yes, that Ontario, like the Rat 1 and 2, is a good, cheap knife.
Second: Yes, ROCKS, MANY, MANY ROCKS. The CPM-3V steel on the TUFF is the same steel that made SurviveKnives famous. I've had several. And the Gayle Bradley with CPM-M4 blade is an outstanding knife with a blade that stays sharp darned near forever. Of course, all M4 blades do.
You are stuck on $30 Ontario knives, and that's great. I have a few of those that I give to grandkids. For serious work, I spend more, get more. LOTS more. It's just a matter of opinion. VW's will get you to work. So will Hummers.
I hope your day is good,

Ha. I'm not stuck on $30 Ontario knives. Read again how I specifically mention the possibility of it being lost or stolen. Anyone who has spent any time in a set of work boots will know how quickly things can go missing on a commercial job site. I wore Red Wings and Carhartt, but most of my tools were trial and error of what was cheap, effective, and expendable. Even then, most of my time working construction I carried a Lion Steel made Sig Tac, and a Zero Tolerance 0350.
I will admit fault on the Bradley, but it doesn't look like something I would want to beat up. Not to mention the tendency of carbon fiber to stain from chemical contact.
Regarding the others, I found out real quick with my Sig Tac that metallic handles suck hard for a laborer job. Even if it's one side. Ever been on a job site where the HVAC isn't up and running and it's -10 degrees outside? Sometimes you have to go gloveless and I assure you, you'll grow a major appreciation for composite and organic handled tools. That doesn't apply only to screwdrivers and hammers.
I also found out that while the blade on harder steels would hold it's edge longer, it was much more convenient to carry something that would hold it's edge a little bit less, but sharpen up really easy with a stone I could carry in my tool bag. Trying to sharpen out a 60HRC recurve with a stone on the job completely sucks. That's actually what made me appreciate American tantos in slightly softer steels. I can get AUS8, (real) 440C, N690, and 14C28N back to shaving sharp in literally under a minute with a little basic stone. I can't say the same for S30V or CPM154, or any higher HRC steel I've tried (including easier chipping in my experience). That's not to say they're not effective, but when it comes to upkeep and hard use, I honestly don't think they're as efficient.
Again, this is just my experience after working decades in autobody and construction. I'm actually out of both of those trades now as a form of employment and only do rare freelance and occasional projects, so naturally, I'm sure there's plenty of people with opinions more valid than mine. I did what worked best for me though and was not let down. If you think I'm emotionally biased towards the Utilitac, you're mistaken. I've been trying to replace it with something more fitting of my new line of work, and have made open criticisms of what it could be better at. The thing is I've never had any other knife that I'd be so neutral towards losing or breaking, but would gladly replace with the same exact example at that price.
