Description

Description

Marking the first application of the AXIS Dual-Action mechanism, the 5400 Serum is a notable addition to the Benchmade lineup. The AXIS Dual-Action mechanism functions like a regular AXIS lock for manual operation, but when the AXIS bar is fully pulled back the automatic mechanism deploys the blade. Benchmade has equipped the knife with a secondary safety system to eliminate "dry fire," which occurs when a blade isn't fully closed.

The Serum is a versatile setup with the ambidextrous AXIS Dual-Action mechanism, comfortably milled G-10 handle, and modified drop point blade. The 5400 model has a satin finished 154-CM steel blade with a plain cutting edge and black G-10 handle with a reversible tip-up carry pocket clip. This is an outrageously clever knife from the crew at Benchmade.

How about the best of both worlds? An awesome flipper with the option to automatically release the blade! Build quality on this one seems to be a little higher than on my other axis models. I'm so glad they came out with this model. Its a beast!!
Broke after 4 days

I had to return mine to Benchmade for warranty repair, because the auto function broke. They repaired it, and had it back in my possession, in about 2 weeks. After that, it has made me leery of using the auto feature. The handle is pretty wide, there is no lanyard hole, and the auto deployment is difficult to activate. Once you pull down on the axis lock, it takes a significant amount of force to pull it down all the way. It's a very good slicer, and there is a nice belly to the blade, plus the manual feature works as expected. The retention, leaves much to be desired. The blade opens very easily, with just a tiny jiggle, and I've had it open in my pocket. Not because of the auto feature, but because there is almost no retention. For a novelty knife, or a collector, I could see getting this. Otherwise, in my opinion, there are better options. Just get a regular auto, or a regular axis lock, not this d/a. It isn't the best at either.
