I don't see what you're reading that suggest that someone carrying a fixed blade is going to use it butter bagels in a restaurant. I wouldn't get cream cheese in my Sodbuster, either. The plastic ones are hygienic and free.
The John Q. stuff is ridiculous. I have a "fixed blade" that has a 3/4" blade and is illegal here in Seattle to carry. But a big tactical folder is perfectly fine. Laws do not always represent reality.
Lol oh Seattle. Hey have you ever been to Eastern or Northern Washington? Maybe you could attest to how non-vexed most people here are at seeing a fixed blade. It's not like we're a bunch of Cowboys either, it's just we don't seem to have that annoying jerk John Q. Public who is concerned about a Buck knife on someone's belt. Maybe that's because in Washington people can open carry pistols wherever they want, and a lot do. So I don't think we have this John Q Public guy flooding his boots at the sign of a weapon like over there in New England. Oh that's not a dig at NE, but pinnah seems to think there's no place except the great rural expanses where the Cowboys roam where people are unphased by the sight of fixed blades.
I carried an Izula and a SAK for two years straight, pretty much every folder I've had has a longer blade than the Izula (including the SAK), and no not tactical folders either. The only time anyone has ever made a fuss was 3 years ago after that Aurora shooting. I went to a pizza shop and forgot I'd clipped the thing to my shirt, and the pizza guy said something like "You might not want to wear that on your shirt after the whole Aurora thing." BIG deal, he didnt throw up his hands up in surrender or call the cops in fear and none of the patrons even seemed to notice, and yeah I was paying attention because I did a look around like "Where's the fire?" I just asked him if he wanted me to leave and he said "I just don't think it's a good idea" and I agreed with the pizza guy's advice to take it off my shirt where I had absent mindedly clipped it on to anyway. Oh and why did I have it clipped on my shirt? It was 100 degrees out and my only set of shorts didn't have pockets, and I was breaking down moving boxes so thought that would be an easy solution and forgot all about it. Since I had no "tactical" folders none of them had clips I could do the same with.
I do find folders more convenient a lot of the times though. Plus the concealment laws are annoying here. It's just simpler to carry a folder to not run afoul of the laws, especially since there's different municipal codes in my state too. However in actual use, I like fixed blades because they're easier to clean up and I just enjoy working with a single piece more, especially when hard cutting tasks are needed. If I need to cut something where I am applying significant force my knife is just one less thing I want to be able to move and shift around. I know people here like to brag about how they just pay attention to what they're cutting, but I don't always have the presence of mind and would rather not have to think it through. It's just one less thing to worry about.
Here is a good example... Changing the serpentine belt on my car. I had everything I needed parts wise, went to loosen the tension idler and my socket wrench couldn't clear the radiator fan housing. It only needed a quart of an inch, so I grabbed the Izula and began carving out a notch big enough to let the wrench slip by. With all the weird angles I would have needed to be extra cautious about it if using a slip joint, and I already had enough to worry about just not dropping the knife with all the awkward angles I was contorting too. When the JOB you're doing is complicated enough, having a simpler tool really cuts down on the Murphy's law events.
My memory isn't good enough to think of any more examples, but typically I tried to cut everything with a SAK first and if I felt like it was kind of "shaky" with how much force I needed to cut, I would go for the Izula instead. Heavy zip ties usually see that happening the most, but any thick and heavy material really.
I got a RAT 1 recently because I just got kind of tired mucking around with two knives where one could probably cover the tasks for both. Not sure yet how it will handle the heavy tasks, but between the SAK and Izula it seems like a happy middle ground. Plus one-hand opening and closing is so much more convenient than putting the knife back in the sheath, and a lot safer than leaving it laying around.
Oh and as far as concealment goes, a pocket knife or folder designed to be clipped on/into the pocket is the only carry option I feel can't be contorted as concealed. I have had people say cops will hassle me for carrying my Izula horizontal on my belt because my gut hangs over it a little. Then if I pocketed it, there's not really anything in the law's language that would keep it from being interperted as a concealed knife. However I asked the attorney general for my state, and they said as long as you're carrying the knife the way it was designed to be carried on wouldn't be an issue: Carrying a belt knife in my pocket doesn't fit that bill to me. Then last, neck carry, I have spoke to cops who said they would arrest anyone carrying a neck knife under their shirt, and to me having a piece of metal hanging around my neck waiting to smash into drinking glasses and cabinet displays like a small wrecking ball. Oh and I know some people will say "Well I have never had a problem with cops" but wait until you have and then let's see how you feel about giving them any reason to throw your ass in jail. Shit happens, having a concealed weapon on you is just a possible 3-5 if something goes terribly wrong in your day. I just don't like to pretend I am as infallible as most do.
