I suspect, but don't know for sure, who passed it along to them, but I just got this email from CRK&T's customer service dept.

Hello!

We heard through the grapevine that your sheath is a little loose on your Ritter knife. We would be happy to send you a replacement if you are interested? The knife is easy to remove from the sheath but should remain in the sheath if inverted. Please send your mailing address to us and we’ll have a new sheath sent to you right away!

Thank you for your support!

Whoever you are, thanks for the help, it's great to see a company really jump in to stand behind their products!!

Hey Doug,

I'm kind of surprised I didn't see any obvious mention of the Mk5 on equipped.org. You may want to add it to the drgear area.

Just a thought.

I ordered two of them this evening!!

Thanks,

Ken

Hi Chris, I am the "grapevine" in this case. Got an email notice of your post as I am subscribed to this thread just as I stepped onto an airline flight, so quickly forwarded it to CRKT before we had to turn off our phones, with the prompt results you saw. I am very pleased with their quick response, that's the sort of customer service that I expect of a partner and one reason I partnered with them.

I was very enthused to read the first part of your post, then my heart about dropped when I came to the part about the sheath. <~> I have carried the RSK Mk5 in its sheath on a ball chain around my neck for a couple weeks with no problems, so I knew something wasn't quite right. While we didn't really design it as an EDC, per se, it still needed a sheath that was reasonably secure. A small inexpensive knife such as the RSK Mk5 always involves some compromises, but I made sure it was safe and reasonably secure before we allowed it to go into production.

As it turns out, seems like more than a few customers are actually EDCing it, which is quite a surprise to me, but I am very pleased they think enough of this little blade to want to do that. We'll have to see how this sheath holds up long term. Thanks for your compliments on the RSK Mk5 and I hope the sheath issue is solved and simply one of those things that happens once in a while with a mass produced product. I and CRKT are committed to making a quality knife that represents a good value and fills the survival kit knife niche I was aiming for.

Thanks. Just a little behind on that, due to significant ongoing and unexpected obligations with Knife Rights and this battle with Customs having sucked up a lot of my time on an ongoing basis. I have redone/updated the pages for the RSK Mk5 and the PICO Lite, which was the most urgent thing I needed to do, next step is to add them to the DR Gear pages and home pages.

Thanks again.

I kinda thought it might be. I have already received a second email from CRKT to let me know my new sheath will go out tomorrow!

The design of the curve in the handle just makes a world of difference between the MK5 and a few other "micro" knives as I call them.

Thanks. Ergonomics of small knives, what I call two-finger knives, is a very difficult part of the design and inevitably involves trade-offs. It's nice to get that sort of feedback that we did okay in that regard.

I have to give credit for that to David White and Dr. Osborne as they were the ones who are most responsible for that part of it. I changed it a bit, finessed it perhaps is a better word, but the whole curvy handle part was part of their original concept.

I received mine in about 5 days from AG Russell (great price). I love the design and I appreciate the tireless work Doug put into it.

Quibbles:

1) The sheath is extremely loose, it almost doesn't hold on at all. I'm going to soften it up with a hair dryer and try to press fit into a tighter hold.

2) The edge is not particularly sharp. My sharpening skillz aren't that great but I'm going to touch it up with a diamond stone.

3) The knotted cord as a virtual grip extender is cool & functional, but the supplied cord is IMO too stretchy. Once you adjust the knot position to butt up against the base of your fist, the cord stretches & you lose some control. I replaced it with orange 550 cord and made a fatter knot; works great now. Not a big deal, just a tweak.

Again, please don't take this as dumping on the product. I am very grateful to Doug and CRKT for going the distance on this unique tool.

How is the fit with you large-handed folks? I usually have problems with wee tools and grips and tend shy away from them. but these look great. Anyone?

I've purchased two and have the same problem .I like the knives but do not trust them to stay in the sheaths.

One thing I did with mine (I cancelled the old order, and placed a new one through AG russell, who got it to me in 5 days), was to run my dog tag chain through the cord loop-that way, should it come loose, it doesnt get lost. It isnt weighted enough to cause any real harm other than a scratch, should it come loose...
