"Ok I have been running mine for 4 days pretty hard and here is what I have observed.
Cutting: It cuts very well the re-curve blade eats up anything you put in front of it. The tip is sharp enough to poke a hole in stuff, I know that sounds simple but some knives have so much belly they lose the tip. The curve is just right to really dig when cutting heavy cardboard, which is most of what I cut in a day and with the christmas season here we are moving a ton of inventory. It cut down about 45 large cardboard boxes today, and this was the lightest UPS day of the week. The handle is comfortable for a folder during extended cutting and the grip grooves are in the right places.
Re-Sharpening: N690Co sharpens back up about as easily as AUS-8 and holds better than 440c, I would venture to say that it is getting close to VG-10 with edge holding. I have yet to compare them head to head, but I was using a flat ground Delica last week and it compares similar to cuts before re-sharpening is needed. A rod or triangle type sharpener is required to work the edge on this thing, I do not really consider this a negative, but it needed noting. It is not very prone to chipping as I hit a staple and it sharpened out pretty quickly.
Carrying: If you like low-rider clips you will love this that is actually a little bit too low for me, but still easily accessible. I always liked how the Spyderco Military stuck up enough to access it quickly. The M1 is still plenty quick it just took a little bit of getting used to. It is thin, but still fills the hand. The titanium lockside is easy on pants and it feels very light while in the pocket. I carry mine in my right front pocket and I can easily get my hand on to access other things.
Deploying/ Defensive use: It opens super fast and super smooth, the studs are easy to find, there is no blade play at all, and it locks up very well. Inertia openings are easily accomplished. It is comfortable forward/reverse and a little less but still do-able edge in with forward and reverse.
Overall I love the knife, it is my new primary carry. I wish it stuck up a little bit more in the pocket, but if thats the only issue I have with a knife then it's good to go. I plan to use the hell out of it. Now I am waiting to see what Combative Edge comes out with next, because I will buy it."
"Hi my name is Bill Brown and I have been a Correctional Officer for 13 years. Do to the nature of my profession I am always looking to find a realistic and practical system of self-defense. Pekiti-Tirsia Kali is just the art I have been looking for practical and very effective. Rob is a very good instructor and his classes are fun and a great work out. As a Correctional Officer edge weapon attacks are a real concern. The Pekiti knife defenses are awsome.In every class Rob teaches stick,knife and empty-hand so every class we train all ranges of combat. Pekiti-Tirsia Kali is a great art for modern times."
"Rob, I love the knife, its my new edc. Thanks and look forward to more products from you."
"I recently became the proud owner of M-1 (S)-0155. I have to say this is the nicest knife I have handled in years. The edge on the N690Co is sharper than any knife I have handled in my memory. The G-10 is very grippy and yet comfortable in the hand. The Titanium side of this frame lock is very clean looking. The clip allows the knife to ride very deeply for a knife of its size!!! I like the tip down set up, but it is a neat feature to be able to change it to tip up if I ever changed my mind, and the "Over travel stop" is just aesthetically cool to me. The serrations are very aggressive, and The whole blade including the serrated area are coated with DLC.
This has become my new EDC, and I like everything about this knife. It even fits my large hand very well. It is designed as a fighter/Self Defense knife, so I always have another smaller Utility knife or SAK to do any utilitarian cutting. I would however have no reservations of using it for all my cutting tasks. i am just taking care of it so that it will take care of me if I need it to.
The Name has special meaning to me as well, because of what it stands for to the maker. The reason I have this knife now is for very similar reasons!!!
If you have the opportunity to handle this knife, or if you are on the fence about buying one, I highly recommend it, you wont be disappointed. Rob is a stand up guy and has been in contact with me since I have had it."
