I have a D4 that has been my carry knife for about 2 months now. The knife has seen more pocket riding then it has done cutting, and I recently touched up the edge with the Spyderco Sharpmaker to make it scary sharp again. Pocket clip shows some wear, but the rest of the knife is about 95%. I'm looking to trade it for some type of Salt series, anything but the Tasman. Would prefer a fully serrated Atlantic or Pacific, but will look at a Salt 1 as well. Let me know!
