I was going throught a box of goofys i packed away and ran across my spring assisted zytel knife. This one cannot be detected via metal scanning but can with x ray. Anyways how do i sharpen this awesome knife ?
 
If its spring assisted how is it non detectable? But anyway I would assume a sharpening stone. Justt don't use a good one the zytel will clog it up.
 
Its plastic, you can sharpen it on pretty much anything. Could probably sharpen it with a nail file. If it were me, I would probably put a convex edge on it with some sand paper and a mouse pad.
 
I would use sand paper from say 400 up to 1000 on a flat surface or a mouse pad of you want a convex edge. then strop on leather with green compound and you should get a nice sharp edge. If you have DMT type of diamond plates those would work great just use lots of water to keep the plastic particles from clogging up the stone. I have seen these blades before I think they are called Blackie Collins CIA Knife and where made for EOD work the assist spring is made form a hard copper alloy so its not magnetic and will not set off Mines that use a magnetic trigger.

That spring is going to set off today's metal detectors. I would also be aware of the likely fact that most states where a switchblade is illegal are not going to specify what the thing is actually made out of. Indiana law, as far as I can tell, defines a knife as anything with a sharp edge or a point that can cut or stab...not a word about steel, bronze, iron, copper, flint, or plastic. It defines a switchblade as any knife opening with...well...a switch. So that thing would qualify. You get caught with that like trying to sneak on an airplane or into a courthouse you will have one serious heck of a time trying to convince anybody that a) it's not a knife, and then b) that it is also NOT a switchblade. All for an item that is a curiosity at best. If that's what you've got it for, more power to ya. If it were me...not so much.

Thanks HQ for the reply. It is not my edc. Just a knife i had to have :).
I don't plan on carrying it on a airplane or courthouse or anywhere else. Btw Its not a switchblade unless spring assisted is considered a switch blade ?

You'll never get it "sharp enough" because the blade is made of simple nylon, it is soft. Zytel is just a marketing name for nylon polymer and it will not take an edge, nor hold one that will come close to steels, or even other composites. You'd do well to give up on thinking that knife is a "slasher". I doubt that you could generate much stabbing force before the plastic pin gives.

That is a gimmick knife, not a tactical Operator deanimation weapon.
 
In Indiana it has to open at the press of a button or the flick of a switch to be a switchblade. I think as long as you have to lay "hands" upon the blade itself and intitiate it opening that way, in Indiana, it is not a switchblade even if a spring helps the process along. That will not be the case in every state, some of which consider one hand openers to be illegal...some with length qualifications...locking or not. It's a crazy quilt of laws.

In Indiana, the only things that are illegal are switchblades and of all things throwing stars (which I am guessing is because some state lawmaker's kid got his eye put out by one). You are perfectly free to stick a 7", double edged Sykes-Fairburn in your boot and carry it anywhere you can carry a little swiss army knife or a watch fob slippie.

Im in California where everything is just about illegal pretty soon it will be illegal to fart lolol. Anyways yea its just a plastic knife dont plan on slashing skin or doing black ops stuff. It is a fun little knife mainly because it can pretty much be held anywhere on clothing when im wearing shorts ill clip the knife upside down on my boxers its light weight small etc. Again i dont edc the knife "anymore" atleast not since those bastards took out the wtc towers. RIP

I was able to get a decent edge on the blade so im just going to call it good i dont want to wear down the blade too much.

Remember this knife is NOT a arithmetic blade the button on top is the blade lock after it has been deployed. Once the blade is back in the handle the button is flat with the handle.

Thanks everyone for the replys:thumbup:
 
I suggest that you investigate CA knife laws, they are quite reasonable.

In CA, you can carry assisted opening knives. You can also legally concealed carry folding knives of any length. -this includes double edged blades (not that it make sense in a folder).

Unless you live in a permanent School Zone or Federal building of some sort, your carry options in CA are huge. -unless you are a minor.
 
How well does it cut? While FRN is tough and chemically stable, it's not particularly hard or rigid.

Cuts wrapping paper and Scotch tape just fine.

Im no minor nor in a school building but work is at a federal facility.
