The KSF one looks cool, but you can see when you un-snap it, it flops forward and the knife could easily fall out. For my $400 sebenza, I would tolerate nothing less than a sheath CRK designed for it. At the thickest part of the sheath where the flap overlaps the front, it is 1 1/4 thick. This is the same as my buck knife sheath. I carried my large sebenza all day today verticle and you could not tell it was there. I wear longer shirts, so its not like it was sticking out. I just put it on and looked in the mirror and I could not tell it was there until I lifted up my shirt to expost it. I have not carried my sheath horizontal yet, but it would look like the KSF one when worn. I like that I have the option to carry it both ways. You also get the head of the snap to cover the snap not being used, so it looks nice. On the inside of the sheath, there is thin leather covering the back of the snaps so as not to scratch your titanium handle. If I spend $400 on a knife, I want the safest, most secure knife sheath there is to protect my investment. Everything CRK makes is top notch and well thought out, and I would expect nothing less with the sheath. Knifeart.com has the CRK sheath for $42.00, thats $3 less than anyone else. I dont trust anything that is friction fit, eventually it is going to get loose and thats a good way to lose your prized sebenza. I like the security of the flap to hold it in place just incase it does un-snap.
