An Update on Using a Bicycle Inner Tube as a Knife Mount

| January 27, 2017 | 0 Comments

Please read this post if you haven’t already.

In discussing an inner tube as a knife mount, I expressed concern that I might just pull the entire knife out — including sheath.

One of you recommended cording the sheath to myself (belt loop, big safety pin, whatever) in case it happened. I did this immediately on my live Clinch Pick.

(note: I deliberately did not tuck the knife all the way into the tube so I could demonstrate the use of the cord on video)

Last weekend I had an opportunity to test it out, but I decided to run without a cord. I wanted to see how bad things would be with just the inner tube.

Saturday was force on force with QSI Training. I used my Clinch Pick a few times, but never under the type of scenario I was concerned about. I used it one while grounded against a grounded attacker (we were both wounded, long story, had to be there), and it deployed easily. I also drew it pre-emptively several times, which meant I could be more mindful of the draw and it was unopposed.

Failures: 0/6

The She Shepherd and I attended our monthly Shivworks practice session the next day. We were doing some in-fight weapon access drills, and I was able to draw my Clinch Pick a lot.

I didn’t have time to keep track (too busy getting worked over), but I’d estimate 30 draws. Most of the time I drew from a clearly dominant position. This made it easier to be mindful and technical.

For example, I would routinely pass both defender’s arms to a right-side overhook, step back with my left foot, and draw the Clinch Pick with my left hand. I did not draw unless I had almost total control, and I felt the situation would stay that way long enough to draw.

There was a much smaller sub-set of contact where I deliberately drew under “less than optimal” situations. For example, an opponent had a wrist tie on my left wrist and was attempting to drive me backwards. I allowed their effort to bring my hand to the left side of my body midline, and then attempted to draw.

This is not the best technique, nor is it the best timing, but I wanted to see how far I had to go to mess up my draw.

This type of thing happened about 8 times. In 2 of those times, the sheath came out with the knife.

Failures: 2/30, or 2/8 depending on if you count the higher-pressure, worst cases, or all of the deployments.

HOWEVER, I still was able to stab the defender both times. In one case, I moved the Kydex sheath with my thumb enough to “unlock” it and then flung it away with the snap of my wrist. The other time I stood on the sheath and then pulled it free during a struggle.

I strongly recommend attaching the sheath to yourself via a cord. You may not need it, but if your knife does get stuck in the sheath it will eventually pull free.

Thanks again for all the tips and the encouragement.
