Hey Greesy,
Your post coincides with my current thinking about Benchmades in particular and knives in general.
I'm not into mega folders, but I do like beefy, substantial knives. The Rukus and Skirmish certainly fit that bill, but also do so with a sophistication and attention to detail that's unusual and impressive considering they're production knives.
Within the Benchmade line, the 755 MPR is a standout for it's heavy duty construction and custom design elements. The 755 MPR uses impressive materials, is very stout and seems to be Benchmade's response--of sorts--to the "Hinderer" designs using thick blades, a Titanium scale and liner lock on one side, and G10 scale on the opposite. The blade steel is M390 super steel--a step up even from S30V. Although substantial in construction, it's relatively compact and weighs about 5.5 oz. The price is comparable to the Rukus, @ $200-$220.
Kershaw has also thrown their hat in the ring with the Zero Tolerance 0300 line, following the "Strider" designs using thick blades, a Titanium scale and liner lock on one side, G10 on the opposite. It's a collaboration between Kershaw, Ken Onion and Strider, featuring some of the unique characteristics of all three--Kershaw's assisted opening flipper, my favorite assisted opening mechanism, Ken Onions blade and handle shape and Strider's heavy duty construction. It's a beast of a knife, weighing a half pound. The blade is S30V and price is comparable to the Rukus, @ $200-$250. Like the Benchmade, it's made in the U.S.A.--Oregon to be exact.
I have a 755 MPR and a ZT 300. They are like chalk and cheese. The 755 is more sophisticated and detailed, the 0300 more brutish and robust. The 755 is a Ford Super Duty, the 0300 a Humvee.
Although the 755 and 0300 share a few basic design elements and are each worthy of ownership on their own particular merits, neither have all the unique elements of a Rukus.
Best,
