I recently received this unmarked EK Bowie. The blade is all black with no markings however the sheath does have an EK tag. I put the extra cord wrap on the handle to make it fit my hand better. There is not a lot of info about EK's out there but it appears the Effingham IL knives are the least desirable to collectors. I"m thinking of putting a better grip on it but if it is collectible I don't want to mess it up. If anyone knows about EK's please comment, thanks.
