I like modern knives that take inspiration from traditional designs. Some example: Spyderco Kris, Spyderco Barong, Spyderco Shabaria, Cold Steel Scimitar folder, Emerson Persian, to name a few. The only knife that I have currently which fall into this category is the CRKT Persian. I'm hoping to get the Spyderco Hundred Pacer next (inspired by Taiwanese aboriginal blades). Any suggestion as to what other knives that I should look into?
