I've been busy working on CAD and tweaking designs. This is the current version of the Sharpy. I changed it to make it easier to open and to give a tactile indication when it's open. Closed, open....... And carried in a pocket. The blade is just under 4". Other details: Weight is under 2 ounces, construction is titanium and carbon fiber. I'm really happy with the way these are turning out. Nice and thin and light.
