I purchased an 810-1401 (blue/black M390) from another member here and I absolutely love it. I’ve always admired the model, but didn’t need another “tactical” knife. I am in “social work” and have others for that purpose. I lusted after the 1401 version when it came out, but only recently had the opportunity to pony up. Glad I did.
It’s big, but I am too, and therefore tend to carry bigger knives anyway, so it’s not ungainly for me. Pretty sure my 940 makes me look fat. The grip is very different (“aggressive” has been used plenty of times before) with regard to the copious texturing all over the steel frame. I wouldn’t call it jimping, as it’s raised beyond the G10 scales, as opposed to cut in, but it’s not sharp. I don’t find it at all uncomfortable, and it does make for a rock solid hold in both forward and reverse grips. It might be a bit much for prolonged use, but I ain’t carrying it for bushcraft, if you catch my drift.
My only gripe, and it’s a very, very small one, is the lack of a lanyard hole. I do love my tactical mancramé, and put lanyards on all my knives. I would love to have one on my 810 just for consistency/habit of pull from my pocket. Of all my knives, the only ones that don’t sport ‘em are this and my 940-2. I guess Osborne wasn’t a fan, and who am I to argue? It’s definitely NOT a dealbreaker for me on this great knife.
In other words, get one.
