More button compression locks?

[silvershade255]

I'm not expecting to see this from the factory, though I could be wrong. I could see it becoming a popular mod. Ferider used a pivot to create a button on an amalgam, and I'm currently testing out using epoxy for a quick and removable job.

I was shocked to see a button compression lock on a DeWalt "Atomic" utility knife at Home Depot.
I bought it, $11.
The blade retention mechanism is better than most; less rattle than on a Milwaukee ute knife.
Easy to swing the blade open one handed (and close it too).

IIRC, didn't Spyderco invent the compression and the button compression locks?

Got the Milwaukee version today

Is that model a compression button lock? My Milwaukees have a button lock, but no compression lock, so...just curious. I don't own that exact model.

Since the DeWalt has a compression lock, you can open it without pressing the button (unlike my Milwaukees, which all require a button press to open--something I often forget to do.)

As an aside, something most of these mainstream-market utes do, is to limit useable blade edge to far less than what's available. Some of the more 'rare' ute offerings reveal 1/2 to 2/3 the blade edge...not just 1/3 of it. Wish more were like that.

Back to the compression lock: Spyderco invented it...has a patent on it (patent US 6,553,672 B2)...so is DeWalt paying a royalty to Spyderco for using it? Seems like they should be...

No, it's a button lock. Just surprised to see these lock types on all these utility knives. Probably already more common in the US than here in Europe.

On topic: A lot of Chinese brands like Vosteed have what they call a "Top Liner Lock" which is similar to the button released compression lock. Vosteeds is one of the first brands I found using this type of lock.

Caribbean or Bodacious (or another model in that size range and with edge all the way to the handle) with a button comp.lock would be really cool... (if I may dream also with FRN handles and a bit lighter).

Didn't the patent run out in the last couple years?

Ooo, good point. If I look up the patent, it says "Anticipated expiration 2021." It also says Status: Expired-Lifetime. That's a little ambiguous. Expired, but a lifetime patent? Or expired for a lifetime? Dunno.

The patent doesn't mention anything about a button, though.

I picked up a ‘Craftsman Folding Knife’ earlier this year for a work beater that has a button compression lock on it. After the patent expired, they are starting to show up more in other makers.

I haven’t been active in this community for very long, but my sense is that the button compression lock or ‘top liner lock’ is the hot thing right now and could stay that way for a while. The budget market sector tends to have the trickle down effect from the high end market sector, hence we have seen tons of crossbar locks the last few years. But those are getting long in the tooth. Right now, the button comp lock is on stage.


It is for this reason that I had hoped Spyderco would be doing anything and everything possible to release more button comp lock models because that is what people want and the time is right now.

I would love to see the push button compression lock across the entire model line. I have trouble with the existing compression lock and the button would solve my issues.

Same. Old semi-arthritic fingers much prefer the button compression lock.
