It all depends, doesn't it? Just walkin' around, whether in the suburbs, city, or the woods, a kabar dozier (one hand opening, locking, easy to sharpen, only weighs 2.2 oz) and the PS4 covers 99% of anyone's needs. UNLESS you're a farmer, electrician, etc, etc. Why carry the extra weight unless you really need it?

One hand opening single blade folders are very practical. I usually find myself holding what I want to cut with one hand before I pull out a cutting tool. The locking blade also enables types of work I would not do with anything else other than a fixed blade. There are new models of multi-tools with one hand opening, locking blades which I find very useful. I do usually carry a single blade, one hand opening, locking blade folder, and I do use them frequently for cutting just about everything imaginable, even in the kitchen.

The single blade folder has several advantages over the multitool. The handling is better, the blades are usually sturdier and the knife is easier to clean. The blades of multitools use to have steel inferior to that of a good folder.
I will not use the weight argument as I carry a multitool as well if I think I might need it.

The single-bladed "tactical" folder essentially splits the difference between a fixed blade and a multi-tool, with an emphasis on convenience.

Obviously more specialized tools would be better depending on the task and the environment, but you can't carry everything all the time.

I don't always have the opportunity to switch between a fixed blade for the sticks, or a multi-tool for an urban area, or a dive knife for on the boat. Even when I do, whatever I choose might not end up being the right tool for the job anyway.

The majority of the time, I've just got my single bladed Benchmade clipped to my pocket and I make do. Be it in the sticks, at the office, on the construction site, or out on the boat.

Yea, sometimes it gets abused because it's not the right tool for the job, but after 10+ years of carrying and using the same tool every single day you get a pretty good idea of what it can and can't handle.

I have more knives than common sense, and yet I find that I grab my RSK folders first for most tasks. As opposed to a fixed blade (I have custom fix blades, a 40 year old Randall, and my cheap and battered mora) the RSK folder is always in my pocket and I always seem to go for it first. The way I hunt, camp, and tramp in the woods... that folder does everything I want a knife to do. Yep, I have an array of multi-tools too. I STILL grab the RSK folder first. Creature of habit, I guess.

Weapon, where fixed blade knives are illegal to conceal?

I like the SA bantam cause of the multi tool bit.

On those locking biners- they usually get frozen closed because someone locks them when they are under tension. Just girth hitch a sling around them and add a bit of body weight and they should unscrew. I have collected several this way at anchor stations where people did a hanging belay before they screwed the gate closed.

My thought exactly. You can't conceal carry (in the pocket or even in the bag) a fixed blade in California. Open carry is out of fashion here either (except when in the woods). But I'm using LM Wave for almost everything now anyway. To address the lesser steel quality of the multitool blade there are several other cutting blades available, just chose wisely what to use for what.

For the pliers - think of them as an Iron Man hand/fingers You will see then a lot of decent applications for them in the field as well as in the urban environment, especially if you add a small bungee cord to keep them closed and hangable.

Also I disagree with opinions about the lack of swiftness in arming the MT knife. At least on the Wave, all you need to do is to loosen the pivot screw a little, so you can open the blade with one hand's thumb easily, and practice doing that for a while.

Has anyone died as a result of the "lesser steel quality" of their blade. I can get Wave blade to the point that I can shave forearm hairs (I use a Sharpmaker) and I do this now and then, most likely before a prolonged field trip. When I am actually going to shave, I go with a cheap disposable razor. When I cut paper, I use scissors. Frankly, I think a lot of the dithering about steel types doesn't translate to real world effectiveness.

I have been carrying my Wave for about two years, and it hass gotten to the point where it opens very nicely with one finger as I draw it from its holster. I am very comfortable with it at this point.

I have a multitool I keep on my belt or in a pocket (it's really small) which offers a short clip blade, short saw, phillips and straight screwdrivers, pliers and an led. This will do almost anything I need while in the city. If I'm in the country I also carry a fixed blade (generic) on my belt. It is for batoning and anything else the little multi's not up to. I sharpen both when I go to the woods.
