Let's quit trying to figure out which maker is the loser in a comparison. All of the companies under discussion do their best to make compelling, well made products and appeal to a wide range of customers.
I count amont my most regular EDC rotation, one Buck, three Benchmades, one Camillus and two Microtechs and one Spyderco. Occasionally a Pro-tech sneaks in, but only around the house
Of these knives, three are frame locks, two are Axis locks, two are Micro-Bar locks and one is a lockback.
Three have titanium handles, two have aluminum handles, one stainless, one Carbon Fiber and one G10.
The knives in question are as folows:
Buck:172 Mayo S30V Ti framelock
Benchmade: 941D2CF Carbon Fiber and D2 Axis lock, 941Ti-01 S30V and Ti Axis lock, 750 Pinnacle 154CM and Ti framelock
Camillus: Talonite EDC Stainless Framelock (did I mentiont it's Talonite?)
Microtech: Old school Socom Elite PE M/A, Amphibian PE M/A both 154CM/ Hard Ano'd aluminum Micro-Bar lock
Spyderco: Native LE CPM-440V PE G10 lockback
I've not had enough history with Camillus or Spyderco to comment on their customer service, but in my experience, Buck, Benchmade and Microtech all get good marks. Buck returned a 25 year old 110 that had been beaten hard (literally) to as new condition for no charge, Benchmade has replaced a damaged blade that was clearly not covered under warranty at no charge and Microtech has taken good care of me on the two occasions where I needed support from them (one totally my fault).
All of these manufacturers make great knives and as far as I can tell they all stand behind them. Most all have special editions that appeal to the collector as well as entry level imported offerings for mass consumption. They have a wide range of product offerings to appeal to a wide range of customers. It should be obvious by my list of EDCs that I've focused in on a certain segment of the market (slim, limited edition tactical folders), but you may be focused on something else like slip joints or drop point hunters, or perhaps how many ten dollar knives you can own. To each, his own.
Let's talk about the knives we like and how they compare to other knives instead of trying to turn knife discussion into a professional sports style arguement about who has the better team.
