Are knife safeties a good idea?

I hate to say it but there is only one saftey that I know of that is truly ingenious and its on a freakin’ clone of the Microtech Halo. Its the same clone @Charlie Mike has posted before.

Here is a picture of it so you can understand the genius. The little tab prevents the button from being pushed but will slide when you put your thumb on the button.

there is on the old darryl ralph meyerco x ray auto. the sas. have to slide over and then push down to open it. pretty ingenious design and was a decent knife when it was priced right for short while.

Does cold steel pay you to mention them every thread that pops up? Autos SHOULD have a safety as well as hair trigger assisted knives. Manuals generally don't have a safety. Enough cold steel shilling already. Criminy.

the tri-ad needs a safety to make it extra safe. :)

cold steel has a secondary safety on some of their Chinese made liner locks like the luzon and Bush folder for example. is very similar to the lake and walker secondary in some ways. enough to be different but same concept of keep liner lock engaged......so guess even cold steel likes an extra safety on some of their folders......
 
IMO additional safeties that prevent opening are or should be expendable.

But I like additional blocking systems that prevent accidental closure of the knife. Lionsteels SR-1/ SR2 and many other Lionsteel knives e.g. have this Rotoblock-System that doesn't add any clutter to the knife but just is an improved lockbar overtravel stop. While it won't make your folder a fixed blade it certainly gives you a bit more of safety at some tasks.
Extrema Ratio's "manual secondary blocking system" is also cool. The ER BF2 series of knives is a series of rather light and slim profile knives with liner lock that still can take a beating. I know that liner locks are deemed unsuitable for harder tasks but as a long time user of this system I have confidence that a BF2's secondary blocked liner lock will perform better than some equally light and big knives with other lock types.

:) I WISH ! But , unfortunately ...no $$$ . Not even an Xmas card or a simple "thank you " . :(

I just love and trust CS , from long experience . I plan to continue recommending unless they fail me . I have reported problems with their QC which is maybe way I never got a check ? :p

On topic , I consider "safeties " to include not just the ones to prevent accidental opening , but also closure - which is even more potentially hazardous . Several recent threads on frame locks slipping closed in use or mild testing . Never happen with a Tri-ad lock . And no need for pins or slide locks even for hard use . :cool::thumbsup::thumbsup:

I'm gratified to see how much respect CS has received on a recent " Overbuilt folders" thread .

The ones with the safeties are NOT Tri-ad locks , and I believes I'm gonna give them a pass . Although the Luzon interested me before the problems with proud blade reared up . ;)

Maybe they could like, pay someone who knows a little bit about folding knives to look at their knife before they put it into production?

IIRC , CS disco'd the new budget version Bush Ranger with the added slide safety ? I wonder why . :confused:

no idear.....but I'm guessing maker couldn't make them up to a needed qc standard....or demand/sales wasnt happening well on the taiwan expensive one.......just guesses though......

I prefer all autos to have them. if they dont I dont carry them. they can open ask anthony cheeseboro anthony cheeseboro he had one open in his pocket i seem to remember recently.

disliking something that makes pocket carry much safer ....... seems far sillier than just ignoring it.

Yes, I strongly prefer safeties. Kershaw says in their warranty that their safetyless knives should be carried in a pocket alone. I just don’t have the space to give a whole pocket to a knife, so I prefer safeties. The one safteyless side opener that I trust is the Microtech LUDT.
 
I can understand why an auto or assist opening knives would have a safety and I take no issue with them ... I prefer manual opening knives but do have a few assited opening knives ... I rarely use the safety but for someone just starting into knives it can be a good tool.

My first exposure was on the tiny Kershaw Chive which has a sliding block safety because it has Speed Safe opening assist. I tolerated it, but never actually engaged it. I also had a Kershaw Leek with the same. Then I had a Benchmade Emissary that also had one due opening assist - never engaged it. My most recent was a Protech TR-5 Auto which I bought due to its size (I like 3- 3.25 inch blades for EDC carry). Unfortunately, this model debuted with a safety.

I’ve sold all of them as I just can’t seem to accept the manual safety - despite having the option to not actually engage it.

No open assist or auto knife has ever opened in my pocket despite 15 years of carrying many examples. Perhaps it’s due to tip up clipped pocket carry. Regardless, I’ve decided to never own another knife with a manual safety.

Am I alone in this intense dislike?

I like safeties in autos. I have had autos open in my pocket, and I have had some pretty bad cuts too.

When I got married, I mentioned that my mom had trained me not to put sharp knives in dishwater because you can cut yourself on a blade you can’t see in the water. My wife said she had never cut herself and kept putting sharp knives under the suds (she denies it, but I am pretty sure she simply did not want to do something my mother suggested.)
She did eventually cut herself, but she still puts sharp knives sudsy dishwater. My point is some people simply accept levels of risk that others will not.
 
I just bought a Buck Inertia with this stupid safety tab on the spine of the handle. It's the worst design I've ever seen. It constantly gets in the way.
 
Never believed in safeties on folding knives.

The way I carry my knife, it can't open by accident in my pocket. If I don't trust the lock to keep it open in reasonable uses for a folding knife, then I ditch the knife.

If I'm asking so much of the tool that I'm worried about the lock on a knife I trust, I use my fixed blade.
 
I had a Launch 5 blem fire in a side pocket and cut a small hole through my pants, randomly happened while I was walking one day.

No ones “close call” compares to a person who used to be on here who was nearly castrated by a Kershaw leek. The short version is that a Leek fired in his front pocket (tip down carry) and the needle fine tip sliced through his pocket, his underwear, and then sliced into his scrotum
 
I've never had a folding knife accidentally open on me, but I've had some good crashes while cross country skiing with the dog and wondered about the safety of having a folding knife in my pocket. I even got to putting a rubber band around it, just to make sure it wouldn't accidentally open up.

That’s the limited edition circumciser leek.
