I posted a while back about how you can simply insert a piece of cardboard into the stock Becker sheath to tighten things up. It works great, but I can see how inserts might not be for everyone. I had been trying for a while to take the advice of many here and removing the insert from my BK7, heating it up and reinserting after reforming it. My understanding is that the BK5, BK7 and BK9 sheaths are identical as far as the insert goes, so this should help out any with those knives.

I tried several times, but couldn't for the life of me get it out by just yanking. I inserted a putty knife on both sides to remove any glue, only to find there was none. I was starting to think there was glue on the bottom holding it in, in which case I wouldn't be able to remove it. After putting a chipstick inside, and working it all around, I realized that the insert had little flanges on it which kept it in. Simply knowing this made it a lot easier to work with. With my new S2, the insert finally came out. You can see the "wings" on the insert clearly.

Using a regular blowdryer on high, I slowly got the insert nice and warm. I them took some of my kids blocks and clamped them down at about the middle of the sheath. I didn't want to close up the mouth too much.

The mouth is still wide enough for insertion, but the middle is clamped and cooling tight.

The insert goes in easier than it comes out. I might take some sandpaper to the mouth and cleanup the previous marks from when I tried getting the inert out.

Can you stock sheath do this?

It even holds up to a really, really good shaking. It will come out if you really try, but for the most part, the retention is wonderful. If I were to use some bigger blocks, I could likely mash down the whole insert, but that risks widening it to the point of making it hard to go back in. I think this works fine.

I hope this helps others. I know it seems really simple to some, but I can't recall anywhere else where the insert has been shown and knowing this before hand would had really helped. I actually have grown to like the stock sheath and think it can be really serviceable.
 
Sweet move. Does the insert scratch up the coating and/or the blade now that it's that tight?
 
Not in the slightest that I can tell. Over repeated inserts and removal, it might loose the matte finish at the points of contact, but that is all the harm I can see it possibly doing. I plan on stripping this one anyway.
 
Even after seeing this thread, I still can't get the insert out. Did you just work it back and forth using the S2 to hold the top of the insert? I tried using channel lock pliers to do that and only succeeded in removing a chunk of the insert...I'm thinking one of the tabs is sewn into the sheath edging. Which will really make it a pain.
 
The insert isn't glued, one of the wings is stitched on. In the first picture here its the wing on the top. You can feel the wing under the nylon, just cut the stiching on that part of the sheath and then it will come right out with pliers using little force. I heated mine up in a 300 degree oven until it was soft then molded it by putting it between layers of cardboard on the floor and stepping on it with the knife inside. Re-stiched the nylon and slid the insert back in and now it fits like a glove. :-)

By the way nice work sqoon, bet you won't miss that blade rattle!
 
How about Kabar just quits making these sh*tty inserts this way, knowing everyone hates them? I've NEVER owned another knife with a sheath that rattled like that!
 
I know the BK 77 has a difference sheath, but do they use the same insert as the BK 7? Or they have the same rattling problem? Thanks for the post it's very helpful.

I say leave the price reasonable and stick with an adequate though certainly not perfect sheath. Throw some innertube rubber in there and the rattle goes away. If they tripled the price and sold the knife with outstanding leather, half the guys would howl for kydex. If they sold it with kydex, then half would howl for leather. Sell it with both and people would want nylon or different leather / kydex and on and on and on.

This way you get a great knife and a workable sheath that you *may* want to replace and you don't have to mortgage the house.
