Question: Is this knife spring assisted?
Document: This is one of the knives that came up when I searched spring assisted knives. It is a nice knife for the money.
It is the heaviest knife i have owned as a medic but it is good quality. I wish it was spring assisted but after playing with it for a while it opens with ease. Exactly what I asked for. No problems with the purchase, it shipped and I recieved within a few days of ordering it.
I'm not a knife expert, but this appears to be a great, durable knife. The blade is a bit dificult to open... requiring both hands to open. I wish Smith and Wesson would make a Border Guard knife with a spring assisted function
Nice for anyone who needs to get a job done reliably, first responders included. While its not spring assisted, it is relatively easy to open, even more so if you have large hands. Will purchase more in the near future.
Didn't think the knife would be this big. It's close to the point of being too big but I like it just like that. Knife passed the paper test for me, but the tip wasn't as sharp as I liked coming out the box. Little sharpening will handle it. Also thought it was spring assisted but it isnt; no big deal though. Overall I like it for $30.
This knife Is HEAVY. But it does the job perfectly. There is no Assisted opening which is the only downfall.
This was bigger than I thought. It's a great piece and a great knife. It's sharp right out of the box, the seat belt cutter is superior to other knives that have one. It is not an assisted open knife. Overall, an impressive piece.
I looked at a lot of knives before I ordered this one. I would not have bought this knife if I would have seen it/held it first. I was looking for an assisted opening knife and this isn't and it is a little bigger than I wanted. It's a nice knife though, seems sturdy and well made.
I bought this believing it was &#34;open assist&#34; or spring loaded, it's not. It is heavier and bigger than you really think. And when I opened it, it still had a burr on the bottom of the blade so the lock, couldn't engage or disengage. I would consider another knife, but for the price... There are slightly smaller versions of this that are more comfortable.
It also looks very imposing especially with its tanto-style blade and its partial serration. Also, the locking mechanism is rock-solid. While it isn't a spring-assist knife, I like the fact that it is simple and maintenance and it is easy to open or close while wearing leather gloves. Holding the knife, there's plenty of rough areas to keep a firm grip and is very comfortable to handle over or underhand.
Answer: yes
