I bought a Tenacious as my starter Spyderco.. I loved it! Even though it was one of their cheaper knives it was still a great knife. I have since given my Tenacious to my nephew as his starter knife, hes just getting into the outdoor lifestyle so I sent him my like new Tenacious with a bright yellow lanyard and a few other survival gadgets. After my Tenacious I bought an Endura 4 (CE in VG-10) and traded for a Zulu in S30V. I loved all my Spydies, but have recently traded my Zulu for a bigger knife. The Endura 4 is still a go-to for hunting/camping/fishing trips.
My first Benchmade was purchased very recently, a Benchmade Mini Bone Collector. I bought this knife to fill in the void of a small work knife that was previously filled by my Zulu. I absolutely love my Mini Bone Collector! I especially love the Axis lock, its very addictive. Now I wish I had the full size Bone Collector! In fact I ordered a Griptilian 550HG over the weekend, it should arrive in a few days. Benchmade is definitely one of my favorite brands, along with Kershaw/ZT and Spyderco.
Now for the hard part.. I have only owned three Spydies and two Butterflies (as soon as my Grip comes in) so remember that when reading this. Since I dont have my grip yet I will only compare my Zulu to my Mini BC. I loved the scales on the Zulu, if I really wanted to I could get some customized for my Benchmades, they felt a little more secure. BUT the Mini BC grip feels much more comfortable. I liked the look of the blade on both knives, maybe the Zulu a tiny tiny bit more, but I would like to change a bit of the blade to make it look better. To clearify, I like the recurve of the Zulu.. the deep belly in particular.. but because of the style of the spine, the blade didnt have the width it could have which would have looked better and been stronger. The Mini BC blade looks amazing as is, and I wouldnt change anything... I mean we would all like to design our own folders but the knife is perfect for style and function as is. Im just a sucker for wide blades, so both knives would look better to me if they were wider. BUT the way the function and feel is what counts. I always love that Spyderco feels good in the hand and feels like a strong knife. Benchmade also feels very comfortable in the hand and feels like a strong knife. All in all I love both brands... but I love the Axis Lock from benchmade more than the liner or lock back from Spyderco (I have no experience with the Spyderco Compression lock or Axis lock rip off). I also love the better variety of Benchmades style of knives over Spyderco. Most Spydercos look similar, but they do have a few knives that look different from the pack, some of them are nice and some are ugly IMO. Benchmade knives have much more variety in style, and Overall, have more sexy knives than Spyderco IMHO. Dont get me wrong, I love them both, and Spyderco has some bad ass, sexy, sick looking knives.. Benchmade just has more of them. There is only one knife I would take from Spyderco over ALL Benchmades... and that is the Lionspy.
Overall, I have a very short list of THREE favorite brands... And BOTH Spyderco and Benchmade are on that list. And this is the list and this list is in order from first favorite to third favorite:
ZT/Kershaw (Mostly the ZT line)
Benchmade
Spyderco
MY Dream Knife is a ZT 30X with a SpyderHole and Benchmade Axis Lock!
