Back when the Rukus was still in production (and long before BM's MAP pricing policy), I obtained one of these for a little less than 170$ shipped. If you're looking for a large user folder, you will most likely find superior and more economic alternatives today (especially given the rising prices on the secondary market.)
Mine was the stonewash/plain edge model, though there was a black coated plain edge model available in limited quantities (however, you would be paying a premium for that option.)
The axis lock is easy to manipulate and truly ambidextrous. The knife is also aesthetically pleasing, although the visible square corner of the tang detracts from the lines of the knife when in the closed position.
My knife came with a blemish spot to the lower left of the BM logo. I was unsuccessful in removing it with WD40, mineral oil, and various other solvents and surfaces. However, the stonewash finish does not wear as easily as BM's black coating.
The scales are a two piece combination of canvas micarta and G10. The scales have a smooth finish, which does not improve grip traction with sweaty or wet hands. There is jimping on the spine and finger grooves to compensate for this, though the relatively straight handle does not allow for an absolutely secure grip (compared to my Zero Tolerance 0301 and Emerson Commander.)
The pocket clip does not offer much retention. Given the size of the knife, I would recommend carrying it in a holster or pouch instead of a pocket.
The blade is heavy enough to allow to one handed opening via wrist flicking. Flicking seems to be the more convenient method of opening the knife, considering the distance the thumbstud must travel via normal operation. However, do note that this will generate a substantial amount of shock against the stop pin. I noticed that I lost a torx screw securing the stop after a month of use, fortunately I was able to use a spare T6 screw from a Kershaw pocketclip in its place.
Flicking will also loosen the pivot considerably. When the pivot is adjusted to a point where the knife will flick open (but exhibit no blade play), it will only take a couple flicks to re-induce blade play. Loctite is a must.
My knife came with a severely off-center blade. As a result, the edge struck one of the backspacers and received a dent while closing. The damage to the edge was minor and could definitely be corrected by sharpening, though it gave me doubts about BM's QC and heat treat.
Benchmade's factory edge leaves much to be desired however. Though the edge held up through repeated use fairly easily, it did not produce clean cuts while slicing paper.
If I had the power to change the design of the knife, I would do the following:
-texture the canvas micarta scales
-increase the tension of the pocketclip
-design the thumbstud as an secondary blade stop
-contour the edges of the scales
-thin the scales down by 1/16" on each side
If you do decide to obtain a Rukus 610, your mileage may vary. You may receive a knife with superior or inferior build quality. However, do remember that the pivot and stop pin screw are susceptible to coming loose.
