Necker sheath dulling demo by Virtuovice

It's the glass fibers in the GFN (Glass Filled Nylon) that dulls the blade. Ever tried to cut fiberglass insulation or fiberglass mats (which are used to reinforce stuff, build/repair certain types of boats) with a normal knife? It's not directly the hardness of the glass fibers, it's the fibers themselves. The fibers add flexibility and toughness to the nylon plastic, but they also dull the knife's blade. I'm sure there are other plastics that are as tough as the GFN but don't contain any fibers.

Anyone know what the Izula and ESEE-3 sheaths are made of? I know it is also an injection molded plastic, but does anyone have more precise info?

Again, not bashing BK&T or Ka-Bar here, the knives are an insane value and in my opinion absolutely unbeatable for the money. I have never seen or handled a knife that was so small, light and easily concealed while being so tough, easy to sharpen and capable of doing tasks one would think to need a much bigger knife for. I am still as much in love with this knife as I was when I handled it for the first time.

I know, I know, but technically speaking the Necker/Eskabar and BK2 sheaths are also IMP. IMP (Injection molded plastic) just means it is a cast plastic which is molten, then injected into a casting thing (can't find the word right now).
 
Oh good. I came over here to post about these videos.

It's a problem I noticed myself with a Ka-Bar sheath.
 
Just tried this out on a Buck Mentor that I thought was just a bum blade, as it was ALWAYS dull. sliced it on my plastic crock stick holder, still razor sharp, sliced it cross grain on my maple strop block, still razor sharp, sliced it across sheath, would NOT even slice paper, I mean full draw slicing. Did it all over again, same results. Guess he's gonna get a new pair of pants!! :)
 
excuse me if I am wrong but... in the video he cuts wood with his bk 14 then easily cuts paper so if your correct about him having a wire thin edge that easily dull wouldn't he not be able to cut the paper after cutting the wood??

It's kinda like, how many licks does it take to get to the center of a Tootsie Pop? The world may never know. ;)
 
My 14 sheath is doing the same thing. I had it shaving sharp and the next day after re-sheathing the knife a few times the edge is completely dull. In fact in bright light I can see that the edge is actually flat!
Solution: I made a leather sheath for it.
 
I made a small kydex one for pocket carry. It is very basic, and I used 2 modified chicago screws to hold it together.
 
So, with all the issues I am hearing of, which do you think would be better? Sticking with the current Ka-Bar sheath that everyone hates, or perhaps make a wooden sheath? I would like to know which would hold sharper edge longer.
 
here's my simple thought

these are not expensive knives.

yet peoplle are expecting top-of-the-the-line sheaths.

tough luck.

knives costing 5x as much don't even come with sheaths.

so, imho? suck it. buy those knives, we don't don't want your biz'nezz...

;) :D :} :V

Im not getting the impression that people want a top of the line sheath with bells and whistles. People want a sheath, that does not dull the knife, thats it. If every other knife manufacturer can do it, then Kabar/Becker can too. Yes, its not an expensive knife, but thats not an excuse to produce a substandard sheath.
 
I can understand frustrations on both sides of the issue but I still come back to having the proper sheath for the knife or don't provide one at all. I have a BK11 and bought it a couple of months ago. It has the BKT Kabar logo on it so I don't know what the age of the knife is but I had thought that the newer sheaths were being made of a different material.

I do know that I can get my knife shaving sharp but after a few days of drawing it in and out of the sheath it will not cut paper easily. A few passes on a steel rod and it's good to go again but it can be frustrating knowing that your knife didn't cut anything but a couple of sandwiches at lunch and now it's not as sharp.

It still is one of my favorite knives and opens beers like nobody's business. :)

Maybe Ethan could chime in and let us know.

I understand that Becker tries to keep costs down but SO many people complain about the damned sheath issues that it's giving them a bad name, which is a shame.
 
I ordered a new Bk14 two weeks ago (received with the older glassed sheath) and showed it to a couple of people at work. They liked the size and feel of the knife but lost interest after learning about the dulling sheath issue and how it was (not) handled by Kabar/Becker. One ordered an Izula the next day.
I like the knife, but the factory sheath will be used as a shotgun target after buying or making a replacement for it.

sorry about my overyly snarky comment there. i don't think i was drinking grapejuice that night. actually, i don't even think i was awake then. weird.

a lot of factory sheaths just plain are junk, and many are just ok. i haven't seen many that make me take notice and go say "wow". when Critter was doing the sheath for his "BK12", he went out of his way to make a pretty good sheath, but as he mentioned, a lot of people just go custom anyway, and throw the darn thing away, so it's almost a shame to go overboard. it's hard to please all people.

at a minimum, the sheath is a useful vehicle for storing the knife, and doing so safety. certainly the BK11/BK14 sheath does that. if you get one that doesn't dull your knife a lot (i've had a couple that fit better), all the better. the new ones are reputedly just fine, but i haven't played with any as yet.

well, people really need a sheath of some kind. getting fixed blade without one stinks. so a good basic functional safe sheath is a nice thing.

people shouldn't be complaining about the new ones. the old ones, yah. the biggest issue is putting that new edge on right away. a lot of draws with the factory edge, which is at 220 or so, should really groove up the sheath nice.

a small jig saw or other blade that fits in there can do up a good groove pretty quickly on the old (and new) sheaths.

back in the day, the original sheaths were some kind of thermal plastic - might actually have been kydex, because when they got really loose, i was able to fix them with a heat gun and a clamp. TIGHT.

pretty strange a new knife came with the glass sheath. try contacting KaBar and see what they'll do.

KaBar has been tinkering with the sheaths since they ran out of Original Camillus ones (don't recall if THOSE were GFN or not), and they'll probably continue to tinker as time goes on. they haven't been sitting on their butts about this. they've even replaced some sheaths for those who really wanted them and called. give them a chance to make it right.
 
I think the neckers are worth their cost w/o a sheath included. However, I think that many people mistake the quality of the knives edge retention due to the sheath. I'm glad that KaBar is working to correct it.
 
Ka bar took care of me when I e mailed them with this issue. I got a new sheath and I haven't had a problem with dulling since. It even fits better with no rattle.

I fixed my issue as well. I just ordered a sheath from Al. Still wondering how recently the new sheaths were distributed. I have only had my BK11 for 2 months and got it from Tomar so I would assume he goes through stock pretty quick.
