If you can find one, you might like the StarMate. It is my favorite Spyderco. It is a Bob Terzuola design with a 3 3/16" blade of CPM440V steel, a hollow ground edge, and a modified spear point. I find it more apealing from an aesthetic point of view than the Military and I prefer the blade grind, especially the tip. I have never heard of a StarMate with a broken tip, but I have heard of several Militaries with that problem. I got my brother a Military because I thought that it would fit his needs better than the StarMate, and this may be true for you as well, but I prefer the StarMate.
Another knife with a 3 3/16" blade of which I am quite fond is the Lum Chinese Folder. I find the leaf shaped blade very functional for almost any chore that needs doing, up to and including slicing and dicing foods. The blade is VG-10, so it should hold up quite well, and the scales are of anodized aluminum. A very pretty knife.
My final thought is Spyderco's workhorse, the Keating Chinook. It has a 3 1/4" blade of CPM440V steel that is about as heavy as any I have ever seen, about on a par with the Camillus CUDA MAXX 5.5, full sized double liners, and heavy G-10 scales. This thing is a tank! Think of it as a heavy duty Buck 110 built with the latest materials and techniques. The design is the classic clipped blade and it is a classic lockback, but done flawlessly and so heavy that there seems never to be a need to worry about an accidental release of the lock. This is not to criticize the Buck, think of it as a handsomly made S&W Mod. 29 revolver of deeply blued and finely polished steel with handsom walnut grips, everything that you think of when you picture the traditional revolver. Now think of a Glock, of an H&K, or of the latest versions of the Sig-Sauers with all of the latest techniges and materials being used to enhance the performance of the item and you have the Chinook, and most all Spydies, for that matter. BTW, it is no lightweight, however, at 7.25 ounces, although it carries fairly easily IWB for me.
