SOG Seal Pup isn't a good backpacking knife - too heavy, not ideal for bushcraft, larger than you need and lower quality steel - and this is coming from someone who had to carry a tactical knife in an elite airborne unit. I don't mean to disappoint - it's not a bad knife - it's just that there are far better choices for backpacking. I've long since sold the two tactical knives I used during my service.
For backpacking I'd suggest a fixed-blade skeletonized handle knife. A fixed blade is always ready to use, can be operated with one hand and all things equal is stronger. My wife and I use the Bark River Necker 2, which weighs only 2.5 ounces with scales (the knife isn't comfortable or as safe without scales)and has a 3.5 in. blade - or you can make scales or a handle yourself - I'm experimenting with a bike tire rubber handle when I get a chance, which also doubles as a material which will hold a fire for a long time. The Bark River Necker 2 is made of high quality steel, is thick enough to be quite strong/durable and has a convex edge which makes sharpening easy. Also it's stainless which means you can use it for food prep without corrosion, yet the steel can handle batoning wood. Other good choices include the Fallkniven WM1 and the less expensive carbon RAT Izula (easy to field sharpen but more prone to corrosion).
As you can tell I'm not in the camp of carrying a razor blade for backpacking. I consider a light small fixed a simple essential survival tool.
And I'm not trying to start yet another razor blade versus knife thread!
