You now live much closer to the "House of Glock" than you did for the last 31 years!

House of Glock, 6A High Street, Willunga, SA, 5172. Ph. 1300 668790

Dunno what their pricing is like, but they do stock the knives according to the ads in the SSAA publications. Can't find them on their pistols4u.com website though.

Three colours should be available: Black, Drab Olive, or Desert Sand, with or without saw-teeth on the back of the blade.

Happy shopping!
