Smith & Wesson M&P 1S Knife Review: What You Should Know…

This is a guest post and entry in our non-fiction writing contest  by LonghairCountryboy

Awhile back, I purchased a S&W .45ACP C as my conceal carry weapon of choice. Then to my joy, I found that Smith & Wesson carries M&P (Military & Police) style of knives as well. Just had to have one of those to balance out the S&W tactical weaponry. Ok here are the technical stats on the knife.

Technical Details

  • 2.9″ blade, 4.2″ handle
  • 4034 Stainless Steel
  • Spring assisted opening
  • Integrated glass breaker
  • 4.1 ounces

Knife Utility

My first reason for wanting a knife of this type was the fact that it has a belt clip attachment. I already carry a cell phone on my right side belt, so actually having a knife there as well gets a little crowded. I carry mine in my jean pocket with the clip, clipped onto the outerlip of the jean pocket.

I can promise you one thing you will NEVER have to worry about accidentally losing this knife. The clip is CRAZY strong. Another reason I wear it just inside my pocket. I can yank it off of there a whole heck of a lot easier than I can off of a thick belt. So drawback number one, the clip is actually TOO strong.

Opening the blade

This is the feature I simply fell in Love with. Smith &Wesson gives the spring-loaded opening a big long fancy name to the acronym of M.A.G.I.C. Magic, hell, it’s a dang switchblade! With the razor-sharp blade encased within, it is a darn good feature to have a safety switch.

In milliseconds, you flip the safety, hit the button located at the hilt, and ZING you’ve got a VERY wicked looking little surprise in your hand. You can also open the blade with the studs mounted to either side of the blade, by pushing it outward with your thumb. The studs are kind of small, and I find it a little difficult to open the blade this way. A redundant method considering the spring assisted pushbutton.


There is a downside to the switchblade action, even with the safety switch. Through the normal course of moving around during the day, I have had the knife suddenly spring open in my pocket because the switch had slid while moving, and pressure had released the blade switch. The same thing happened while I had it on my belt once as well. This has only happened 2 times in the 6 months I have owned it, and I carry it daily.

Size and Comfort

I really like the size and feel of the grip. In a full grip position, it sits firmly inside my hand, with a good 3/8 inch between my hand and the serrated edge portion of the blade. I would have no concerns if using this in a self-defense situation. The Scooped Back Serrated Drop Point Blade is intimidating looking despite its short length. As it should be, since the edge on this blade is like a razor. It would inflict very serious bodily harm if utilized.

Integral Glass Break

This is another great feature. Not only will it easily shatter a car window (I’ve tried it), it will also make someone step back and think twice if you slam it into a nice sensitive spot on the body. Might be agood option to try before resorting to evisceration.

So, overall, I am very happy with the knife. It keeps an edge well, is comfortable, and multipurpose. The finish holds up well after 6 months of constant carrying. I would highly recommend one of these as a back-up means of self-defense. Even as a primary means, if you do not like guns.

You can find them from anywhere between $ 35.00 to $ 50.00 depending where you shop. I purchased mine from a vendor at a local gun and knife show. Talk them down. They want to make the sale. You should always have some means of self-defense on your person at all times in this day and age.

    Sounds like a good piece of hardware!

    I carry a Kershaw Leek, currently without the serrations. One of the best handling knives I’ve used, but not as heavy duty as this S&W.

  2. Old Hillbilly says:

    Thanks for the great writeup Country Boy! That is a good looking knife. I need to order one. Have you had any trouble with the automatic-opening button? I have read reports that some of them fail pretty quickly. I am a knife dealer and just looked it up from my wholesale supplier and my cost is around $27. By the time I pay shipping & handling and credit card fees there is no way I can do it for the $32+ price quoted at the Amazon link in the article…and it qualifies for free shipping to boot! One thing that needs pointed out is that while this knife says “Smith & Wesson” it is not made by S&W but rather is made in Taiwan and imported by Taylor Brands in Kingsport, TN which also imports Schrade knives. This is not to put down the knife, just stating facts. Lots of affordable knives are now made “off-shore” and are decent knives. Thanks again for the review.

    The version I have of this knife is the 1BS. No hilt button, just the thumb studs. It’s cranky about opening with the studs. I’ve found that I have to squeeze the blade into the hilt a time or two then try to open it to have any success. When I carried it it never once opened on it’s own though. I’ve spent hours flicking it open to try to loosen it up but after it sits closed a while it goes right back to being stiff. Good blade, plenty sharp enough to cut through a seat belt and since it has the glass breaker I’ve taken to leaving it in the car for emergencies.

    I now carry a Kershaw Burst 1970ST I picked up off Woot for 12 bucks + shipping. That knife is a dream and an easy flick of the lever at the hilt and it flies open. If Woot ever has a repeat of that deal I’ll be picking up more.

  4. I picked up the S&W ExtremeOps this weekend at the San Antonio gun show for $15. This is to be my everyday carry. The knife came dull as a butter knife but I have managed to put a decent edge on it. Everything else is surprisingly nice for a $15 dollar knife. Lots of surface serations for easy grip and the flickability is good. Blade does not have a lot of play in or out of the handle. Made me smile on the way out. Now if the vendors would carry something other than AR15 carbon copies with a bunch of tacticool non-sense it would have been a good show.

  5. Keep in mind that in some jurisdictions your spring loaded button operated knife, also known as a switch blade, may be illegal. Except for Law Enforcement, that is the case here in Ohio. The statute here reads that to be legal, you must be touching the blade to open the knife. I carry a Camillus Blaze Robo assisted folding knife and a Camillus Heat assisted folding Rescue knife. Either of these can be opened with a thumb stud (except my hand is a bit too small), or by pressing the lever at the hilt, which is actually the back side of the blade, so in either case you’re touching the blade to open it. Both good knifes, the rescue knife having a special serrated blade for cutting fiber (seat belts, rope, pant legs, shirt sleeves, etc) and the glass breaking stud. The only one I’ve seen nicer than this one is carried by a friend who’s a paramedic, and his (don’t recall the brand) also had the wrench cutout to open an O2 tank valve.

    Over the years I had a couple of auto openers with safeties. I always disabled the safeties as I don’t want any delay if I need a blade in a hurry.

    One day I nearly fell in a deep hole and in the contortions to save myself one of those knives opened in my pocket and stuck me near my favorite parts! I guess the safety is there for a reason.
    Switched to non-auto ColdSteel folders after that.

    I may get one of these S&Ws to keep in my truck door panel. Never have too many knives.

  7. SurvivorDan says:

    Don’t forget folks. Juries think anybody who defends themselves with a knife is suspect.

    DA, ” He brutally stabbed the other fellow…” or “He viciously sliced him open and his guts fell out in a pool of blood…..”

    Last resort…..of course.

    • Next to last. My carry gun is last.

      I do however agree with your analysis of the jury. Whether or not its a gun or a knife, you better know your state laws on lethal force in any case.

  8. LOL, Dan- there is also the obverse: “The perp looked at his eviscerated guts now hanging to his ankles creating a feces puddle around his shiny new Reboks and realized he’d picked the wrong person to perp on, and he fell to his knees in effort to retrieve his innards… as the victim walked quietly away.”

    • SurvivorDan says:

      Rather graphic description of a defensive knife deployment old sport.

      But, point made.

      You were probably a cutlass/dirk swinging pirate in a previous life
      JSW. “Aaargh! There’s knife work needs doin’!!!”
