I don't know if this is where this should go but...
Quite often when you buy a knife with sheath in the lower price range $20-40 the knife will fall out of the sheath rather easily sometimes if the knife has no guard and the sheath is deep enough you can soak the sheath till soft then insert the knife untill an inch or so of the scales are into the sheath then clamp off as shown and dry by a heater or other mofderate heat source, you can oil the blade or wrap in saran wrap to help protect blade, not applicable to every knife but works on many, the one shown is an "English Trade knife" from Crazy crow, half a dozen other vendors sell what looks to be the identical knife/sheath.I usually make my own sheaths but am getting lazy as time goes by.
