KnifeWorks is pleased to announce Doug Ritter's long-awaited RSK Mk1 with Bohler-Uddeholm M390 third-generation powder metallurgy high carbon stainless steel, finished with Doug's exclusive heavy stonewash. Hardened and tempered to HRC 60-62, this evolutionary high-tech blade steel offers improved edge holding, greater toughness and higher corrosion resistance. Even better, the RSK Mk1 with M390 steel is an even more incredible value at only a $5 more than the original!

Not everyone can afford $200 or more for a top quality folding knife. Even $150 is pushing it for many. However, everyone deserves a knife they can trust their life to in extreme conditions, a knife you can bet your life on. The Doug Ritter RSK Mk1 meets that goal at an affordable price. This is a collaborative evolution of Benchmade's Griptilian folder produced exclusively to Doug's . "RSK" stands for Ritter Survival Knife, an indication of its strength and reliability, but it's really a perfectly practical everyday carry knife. Thousands have been sold and are in daily use throughout the world, from urban city to Alaskan wilderness to Middle-Eastern war zones.

Doug has now upgraded the RSK Mk1's blade steel to Bohler-Uddeholm's M390 third-generation powder metallurgy high carbon stainless steel. Hardened and tempered to HRC 60-62, two full points more than the original, M390 provides even better edge holding, while also improving toughness, as well as increased corrosion resistance. M390 represents the latest evolution in knife steel technology, providing improved performance in every respect over the original's still highly respected CPM S30V blade steel. Essentially, M390 is S30V on steroids, and it is now available at a value price in Doug's RSK folders.

The sturdy, ergonomic glass-filled Noryl GTX handles, stainless inset liners and patented super strong ambidextrous AXIS Lock are pure Griptilian, proven over the past decade as a Benchmade classic. This is a handle that just plain works with a secure non-slip grip and a pronounced finger guard for safety, as well as a full-size lanyard hole. The pocket clip is reversible.

What helps sets the RSK Mk1 apart is Doug's wide-chord and robust drop point blade design. This is a traditional blade style, very strong all the way to the point and very versatile. The 3.34 in. (8.48 cm), by 0.114-inch (2.90 mm) thick, blade has a high, flat grind for cutting ease and strength. This grind makes for excellent slicing geometry.

The blade's spine incorporates a prominent ramped thumb rest for enhanced control and security. This thumb rest portion of the spine also does an excellent job creating sparks using an artificial flint and can be used with the knife closed for added safety.

The blade finish is a strikingly beautiful, but very practical "stonewashed" tumbled finish that also serves to seal the metal's pores for added corrosion protection and strength. The result is a subdued finish, but one that is smooth and just barely lustrous. The finishing media and process was designed expressly for this knife to get the exclusive finish quality enhanced properties Doug desired.

Dual thumb lugs provide ambidextrous opening, easy even with gloves on, completing the fully ambidextrous nature of the RSK Mk1.

Great design.....bad idea using M390.....go back to S30VReview by Scott
I had the original RSK1 in S30V. A fantastic knife that wasn't so expensive that i felt like I was wearing around a Rolex. I bought this latest version in M390, and ran into a problem with the steel. The Ritter blade has a wide, thin edge which is fantastic for a slicer, but that wide edge puts a lot of twisting torque on the edge during certain tasks. I was doing your regular baton work on a 2" Red Cedar limb to see how the edge held up to this common survival task. When I sharpened the knife on a bench stone I noticed that there was a hump in the edge bevel. Sure enough, the edge had torqued to the side during the baton work, ruining the blade. Benchmade was nice enough to replace it free of charge, and they reported that there was no problem with the heat treat. There is probably a reason why BM uses S30V in their hard use survival blades.....because it is MUCH tougher than M390. Big mistake Doug using M390 for your knife line. I love M390 as a cutting steel, but it simply does not have the toughness and elasticity of S30V. Go back to S30V please. (Posted on 8/22/2016)
GREAT EDCReview by Nate
The ergonomics are excellent and the blade came razor sharp out of the box. Although it had a bit of blade play (which is somewhat typical for benchmade's axis folders), minor adjustments on the pivot screw will fix that. Knife Works' customer service was excellent as well. I hope to purchase more products from the site in the future. (Posted on 4/4/2016)

I got my RSK MK1 from Knifeworks and had a chance to play around with it for a while. I can say out of all my folders, this has got to be one of the best folders ever made. The handle is grippy, the lock solid and oh yeah, the blade. Doug Ritter's blade profile is not only utilitarian and efficient in usage, but also pleasing in looks yet conservative in appearance. The M390 steel seems to hold an edge quite well and the stonewash finish not only protects the blade, but adds to its sharp looking appearance. While the original Mel Pardue blade on the original Griptilian is good and will do the job well, I feel the Doug Ritter blade is better in looks and usage. If you’re looking to get a Griptilian (or add to your Griptilian collection because as everybody knows, there’s a whole bunch of different versions out there), I highly recommend getting the Doug Ritter RSK MK1 version. You're going to like it! (Posted on 2/28/2016)
I've had one for over 5 years...carry it always! Deploys faster than an auto. (Posted on 12/7/2015)
I'm very impressed with the overall feel and quality of this knife. The M390 blade was the deciding factor in buy this and it does not disappoint.It actually sharpens to a slightly more acute edge than my 710-1401 and that's saying a lot. No doubt the long thin flat grind is largely the reason for that. She's not the prettiest girl at the dance but she feels great when you hold her. Blade is centered perfectly, the stone washed finish is real nice and will work great with the new carbon fiber scales on order. The deep carry natural finish titanium clip I in installed works and looks like what BM should have used. To sum it up you can't go wrong buying this at this price I consider it an investment.

Combines M390 super steel with the legendary and proven Axis lock Benchmade Griptilian. I honestly can't believe its $140, given the materials; Amazing! (Posted on 3/24/2015)
Doug Ritter, Knifeworks, and Benchmade folks did it again. You have already viewed the reviews of Doug Ritter RSK MK1, Stone Washed S30V Blade. It is undoubtedly one of the knife with most value under $200, RSK-Mk1 has steel upgrade. M390 is one of the premiere stainless steel than can have on knives around. It is equipped with Ambidextrous One Handed Open and Close feature of AXIS lock, it is the best folding knife around. (Posted on 10/7/2014)
