Hi Guys,
This is an idea I goofed around with 5 years ago. (please note - the website is not active, but I still own the domain, tooling and product.)
The BladeKeeper was designed to protect pockets against knives, tools, lights etc. It was sent out to about 100 testers circa 2007 but never reached retail ops, even though I still own inventory.
There are many people on BladeForums that use their knives as tools and use them hard, many others keep their knives as collector's items or handle them with "kit gloves". If you are one of the latter, the BladeKeeper is not for you. The BladeKeeper was designed to be gentle to pockets and knives, but steel on aluminium contact or can possibly scuff, scratch or wear the handles and scales of knives.
The BladeKeeper can be "crimped" semi-permanently and put through the washer 1000's of times, or can be removed daily. Due to the nature of knives and tools and the million variations, not every knife clip or tool clip will function with the BladeKeeper.
i have some being sent out for a PVD coating (DLC and couple other AlTi) to further reduce friction, scratching and to make the BladeKeeper blend in more.
A few pics below to demostrate:
