Phil-

I dunno which "flat edge" you used to adjust a scope. Both blades are flat-ground. But there are three screwdrivers on that knife, and they are for turning screws. I bought a used SAK and had to very carefully tap the tip of the main blade with a plastic mallet to straighten it because a prior owner had used it to turn screws. He must have put some effort into it to bend the blade tip. I also have seen blade tips broken on pocketknives, and not just Swiss Army knives. Throwing a knife or using it as a screwdriver are the most common ways in which knives are damaged.

BTW, if a particular SAK lacks a true Phillips - head screwdriver blade like your Tinker model has, the small screwdriver on the can opener will turn most Phillips-head screws.

You may be interested to know that the little cross on the blade tang is the Helvetian Cross from the Swiss flag. The Helvetii were the Swiss tribes through which Julius Caesar had to fight his way en route to Gaul. They later joined to form the Swiss nation.

The little thingee that some think is an umbrella is the stylistic representation of Wilhelm Tell's famous crossbow. It also appeared on Wenger blade tangs. Current SAK's no longer carry that image. I think I'll write the factory and ask why. On the other side of the blade, where yours will read "Switzerland", it now reads "Swiss Made", to ensure that consumers know the knives remain Swiss, not made in China, etc. (This is the explanation given to me by the factory. I didn't guess or get it off the Net.)

I hope this is of interest and may save someone's blade tip from being used as a screwdriver! If you DO ruin a blade, Swiss Army Brands can usually replace it.
