Cryo on the way!!

[Andy S]

I've been looking at the zt0560. But I've never had a flipper before, so I thought I would try something alittle less expensive before I pull the trigger on the 560.

I've read about removing the assist in the Cryo... Is this something that would make the deploy more similar to the 560?

The Cryo has virtually no detent without the torsion bar. I wouldn't recommend taking it out and if you do just be aware that the knife will most likely open inside your pocket. It's really nice though man you like it great for the low price.

Toward the end of the 30 page Cryo thread here, there are pics of someone adding a detent to the blade of their Cryo with a diamond Dremel bit.

As you probably know the 0560 has bearings in the pivot which can't be match in a knife without them. So while it is possible to get a great functioning detent in the Cryo (with the torsion bar removed) the deployment won't be close to the ease and smoothness of the 0560.

I've made my Cryo into a manual knife. I took out the torsion bar and drilled a pocket for the detent ball in the blade, and it retains just fine without opening. However, the flipper tang is essentially worthless unless you really throw in a strong flick of your hand.

The blade on the Cryo is small, and light. The short length of it (and what seems to be a matter of weight placement towards the beefier rear end of the blade) makes the momentum to carry it open almost nonexistent. In the 0560, you have a long, heavier blade, that will gain all the momentum it needs to swing fully open, especially when combined with a strong detent that causes a large amount of kinetic energy to build as you apply force to the tang in order to overcome the detent. This can't, and doesn't happen with the Cryo, and it requires the spring assist for it work with the flipper protrusion.

That being said, the thumb stud on the Cryo works fantastically, and you can slingshot it open very easily and quickly, as well as flick it open with the thumb stud with practically no effort at all, even with a proper amount of detent strength should you make it a manual and drill a hole for it.

Hope that helps. I plan on making a video about the Cryo being a manual knife, explaining what I did/used as well as the caveats.

How did you determine where to drill the detent hole?

After even minimal use, the "detent" ball bearing in the lock bar should be leaving a visible arc trail on the blade surface; use the end-point of the arc as the spot to drill the divot (try to be very accurate, if you place the divot past the end of the arc, the ball will not seat all the way into the divot, resulting in weak detent).

I got the Cryo yesterday and it is the best $30 knife I've ever had. I need to loosen up the clip alittle, but other than that it is a sweet little blade!
