I have absolutely no idea.
however, whatever this "
strider" is I will reiterate about cordura sheaths that have kydex inserts:
-buying kydex inserts and modifying them would require a section of the shop to be dedicated to the task. that section could just as easily be used to keep the production flow of the knives going faster and more efficiently. you still might not get a perfect fit.
If a company has a knife or series of knives that they have in production for several years, you can purchase a large quantity of a kydex insert style sheath that the maker
knows fits that particular knife or series of knives.
however. if they make 4 version of that same knife, a 3/16 version, a 1/4 version, and a 5/16 version, then they need 3 versions of that sheath.
now, if they have (like busse does) 30 different knife models - then they need 30 or more different sizes of sheaths. now, assume that each given model is only going to be in production for 3 months, so instead of buying all of the sheaths at once, you now have to buy a stock of 3-6 different sheaths every three months, varying in size from production run to production run. maybe the sheath maker will have what you need, maybe they won't.
you can only hope they do, cause if they don't your production schedule is going to be set back, maybe 2 weeks, maybe 5 months. depends on the sheath makers production schedule. why would you need that many sizes of sheaths? won't one sheath fit multiple knives? yes and no. it will sorta fit knives that are longer or shorter. not knives that are wider, and not knives that are thicker. if the knives are thinner, or less wide, then chances are it will be floppy in the sheath and customers will complain.
but wait, busse can't have 30 different knife models... they couldn't possibly have that many production runs within the past 4 years. yep - heres a very, very, very off the cuff list off the top of my head of the different production runs of knives (10 knives or more) that would require a specific size of sheath:
1 - SF Natural Outlaw
2 - sow version (slightly less tall blade)
3 - Active Duty
4 - fat Active Duty
5 - off duty
6 - Force One
7 - NARK
8 - 1/8" presentation grade NARK
9 - Meaner Street
10 - Leaner Meaner Street
11 - model t version
12 - Game Warden
13 - Fusion Steel Heart
14 - heavy heart
15 - moash
16 - fmoash (slightly less tall blade)
17 - Force one
18 - Satin Jack TAC
19 - sjtacle
20 - Badger Attack TAC
21 - batacle
22 - Fusion Battle Mistress
23 - fbmle
24 - ffbm
25 - ak47
26 - ruck kensai
27 - skeleton key
28 - ash1
29 - ash1 le
30 - the thicker version of the game warden
31 - sus scofa
32 - war boar
33 - hell razor
Busse is unique in that they are a production company that runs like a semi-production custom shop. they produce more knife models then a normal production company, and still have a completely custom section of their bussiness.
If you can think of a company that produces as many knife variations as busse does - in the QUANTITY that busse produces them, I'd like to hear it (just out of curiosity sake, i'm not trying to insinuate they don't exist, I'm just somewhat limited in my knowledge of the knife world).
the only example I can think of is bark river, and I don't know if they produce as many knives, or wether they include sheaths with their orders.
