Can anyone give me some advice on some options for lashing the sheath of my Leatherman Wave to the shoulder strap of my backpack?

I would not lash it upside down. The sheath doesn´t hold it firm enough too prevent loss if the button opens accidendly. I would only lash the sheath to the strap if there is an extra strap for adjusting or holding equipment. You could use a generous amount of paracord or duct tape to fasten the sheath. Make sure to run some of the tape or cord through the belt loop.
I would not run the lashing over the padding of the strap. This could get very uncomfortable.
If you can make a special sheath for the backpack this would be the best solution.

Saw this on some Veteran's Day movie did ya <img src="/images/graemlins/grin.gif" alt="" />? In practise, unless your going to take out every asian american character actor in Hollywood or cut your best friend free rappeling down a mountain it's no more convenient than a secure pocket.

I'm gonna second that. The problem with lashing things to packs is, if you lose your pack, you lose that item as well. Keep it on your belt. Be like Batman!

You could you zip ties.

Zip ties, double-sided Velcro wraps, BladeTech Tek-Lok clip...but with anything, you could lose it, as others have noted. I prefer my knife to be in my pocket, but I do have a small sheath knife on my Camelback HAWG, attached with a Tek-Lok. (It's the pack I use when rappelling, too.)

Prussik Loop
Someplace on the web should describe this knot.
Sorry, I can't describe it <img src="/images/graemlins/smile.gif" alt="" />

I have no opinion whether this is a good or bad thing...just trying to answer the original question you posed.

The prussik knot is not intended for that kind of lashing. It may work itself loose if there there is no load and much movement on it. In most situations it may be possible to tighten it before the tool is lost but it would be uncomfortable to check and tighten it frequently. If the tool is in the loop it´ll dangle which is IMHO a bad thing.
BTW: I really liked the idea of lashing equippment to the shoulder strap of my backpack. I was quickly cured by trying it in real life.

Hi mpmassie,

You could use rings of bicycle inner tubing.

If you fix it permanently you might want to consider a second sheath to easily transfer back and forth.

My personal preference, like many posters here, would be to carry a knife on my person.

Upside down, bad. If you really, really, really must attach it to your shoulder strap, I'd go with one of the more secure knife/single pistol mag pouches that is designed to be carried horizontally on the belt, such as the single cell SpecOps SuperSheath, and THEN add a bit of bicycle inner tube around the outside of the sheath to keep it TIGHT.

Either that, or a small utility pouch attached to your shoulder strap that would hold your Wave, a flashlight, lip balm, compass, you know, the stuff you need frequently so you don't want to put it in your pack proper.

One question I suppose is what kind of pack are you using? Some of the newer styles ahve molle webbing on the shoulder strap, so you could add something VERY secure that has, say, velcro and a fastex buckle, such as the USGI or EssTac single pistol mag pouches. But security is going to be a big concern no matter what you have up there.
