Definitely always 710, excellent SD & working utility knife, for around $150 great price2value!
Pros: 4" blade, recurve with sweet spot int the right spot, partially serrated, sharp thin point for deep penetration, excellent slicer, light weight, thin g-10 handle profile for pocket carry, d2 tool steel tough enough for most work yet easy to sharpen with proper tool.
Cons: too narrow flat handle, no finger choil on handle for better grip when deep thrusting, d2 steel had 2 tiny rust spots when arrived from seller but none now after polishing blade on belt sharpener, regular not a deep pocket clip worn only in tip up position, I prefer tip down carry.
Solution, keep d2 clean and dry, replace regular pocket clip with deep pocket clip, replace g10 scales with custom oval shape for better hand fit, sharpen to 15 degrees and mirror polish blade edge.
