Question: Can i use WD-40 on it?
Document: Excellent impressive piece. Anyone buying it knows its not practical to use, but awesome to have as a collector item.
It's surprisingly bright for a little LED, and the button on the light is easy to operate and clicks on and off, so no constant pressure is required to use it.
It is the ultimate Swiss champ, complete and surprisingly not too big.I definitively recommend this product for those who collection or use this pocket monsters .
Victorinox Swiss Champ XAVT is amazing pocket Knife, it has all the tools you will need in an emergency, you can use it in various works and obtain successful. I recommend.
The blades are very high quality steel and razor sharp. When shown , the knife gets rock star attention. For what you get , the price is astonishingly reasonable. Dont buy this to admire; use it. My cudos to Victronox.
BUT, for use ?No, I am not going to use it as regular tool.Because, it is a kind of Luxury product with sensitive electronics functions.I will say, this is Piece of Art, A Piece Of Really Fine Art.
Great collectors item. All the tools & implements work just like a normal Swiss Army knife but it's big, heavy, and not practical to take & use in the field. Great conversation piece and your drinking buddies will get a good laugh! !
It is because i collect them and it is an ULTAMATE collectors item. It is usless otherwise. Besides no one wants to use a $230 SAK. Its only good use besides a collectors item is a pape weight. Think strongly befor you buy this knife or you will be wasting your hard earned money.
Again, nice touch. And it makes changing batteries a snap.I don't really know what else I can say about the knife, other than all the tools are of high quality. They're solid and will see a lot of use from me.Some people complain that the knife is too big to use or carry in a pocket. I say, "Nonsense!".
Nice To Have, But Almost Impossible To Use.Why wasn't it designed to separate into 3 sections, which could each be usedindependently?Include additional panels to engage on a bare side, virtually creating3 Medium Knives from 1 Humongous Knife.And of course, they could be reattached for Shock & Awe.Then I could justify a purchase.
Answer: no
