I edc a Leatherman Charge with a clip and I love it. It is however pretty heavy so it doesn't work well with thinner pants (dress pants).

I also have a Leatherman Kick with a clip that I keep in my school bag. It is more comfortable to carry clipped than the Charge, but it doesn't have a saw, file, or scissors. Also, It isn't as comfortable to use as the Charge (the handle edges are thinner).

That's pretty much your only options with a clip right now.
