I was surprised to find a P.I.T.S. M390 Sprint Run Slipit at S&R Knives (my favourite Canadian source of decent blades in the 1990s.) Been looking for this particular P.I.T.S. version for a couple of years now.
Needless to say, I had to order one, which came today.
This knife has a fantastic fit & finish. It has a solid "lock-up" for a non-locking folder. Unlike my other sub-3" bladed Slipits out of Maniago, I will not have to relieve the edges of the Spydie hole & of the blade's spine. There is no sharp gimping. There is nothing sharp anywhere, except for a surprisingly keen edge (out of the box).
The spring action of this non-locker is quite firm, so for now, it's a two-handed opening & closing knife. Seems I'll have to get back to exercising with my (40 lb grip) hand exerciser, so that I can easily deploy this powerful folder.
I swapped out the original wire clip for a Lynch NW stonewashed clip that I had on an AEB-L Urban. It was like they were made for each other.
Just curious. Does anyone know which of the Maniago companies completed this particular P.I.T.S. M390 Sprint? I have heard somewhere that Fox Knives completed the Damasteel Urban.
The fit & finish of this P.I.T.S edition seems on par with my Damasteel Urban. Did Fox also make this knife?
Cheers, 1penge

I can’t comment on the maker, but can say they do break in with use.


I'm happiest with Micarta and Tool Steel.
Top four in rotation: K390 + GCM PM2, ZCarta Shaman, Crucarta PM2, K390 + GCM Straight Spine Stretch.

Don't know which Italian maker they use but my P.I.T.S. sprint opens with one-hand pretty easily. I was kind of difficult at first but it's no issue now
Of all the things I've lost I miss my mind the most!

I always assumed these were Fox. Certainly doesn’t feel Lionsteel to me.
I had one of the original models, with CC number, and that one could be flicked. My m390 sprint version is much firmer but still one-handed.

Thanks all.
Perhaps Mr Glesser would clear up who's the maker of the M390 P.I.T.S. Sprint?
For a non-locking knife, I generally appreciate a stiffer action. I'd think that eventually I'll be able to slow roll this blade a little easier. In the meanwhile, many thumb push-ups.
For now, as with my traditional slip-joints, a two handed opening will be the way to go.
My knife's blade has no play in any direction. Once broken away from the "detent" grooves (in either closed or open position), my blade glides along nice & smooth. I've resisted the urge to get out my T8 driver.
That's a lovely pairing with a Sebenza. Like on my P.I.T.S., the clip finish is almost perfect match.

Hi 1Penge,
We don't mentioned the makers as a matter of policy, but the folks 'round here usually figure it out.
