Willie, I honestly don't remember, but it may have been
here. But they're available from several internet dealers who carry Victorinox. It was about $3.00 when I purchased it and I included it in a larger knife order or the S&H would have made it fairly expensive. I see that they suggest using a SASE with your order to avoid that - good idea.
There's a Hunter Plus model available for a decent price (shop around) that includes, among other things, the screwdriver.
