You are not even kidding that it would void the warranty of a Benchmade! Whew...
I literally had a dozen Benchmades, that is a nice hunk of change for a user, not a collector.
I had a problem with a BM Stryker, and was amazed to find it had 4 different kinds of screws on it! Yes, four! I know it takes a couple different kinds of screws to put a knife together, but this thing had different screws for the same application...arrrgggghh Went on the BM Forum one day, asked them why...they just ignored me...that and other reasons...I sold/traded them all.
But I found something that whoops every folder made as far as speed of deployment goes...The Mighty Emerson Commander.
With Emerson knives, you do not need a tool box full of Allen this or Torx that, all you need is a damn Swiss Army Knife or a Gerber Multi-Tool, something simple, to work on these knives...and I have taken the Commander apart and it is very easy to re-assemble. No need to buy yet another different alien tool, or the same thing in a different size to work on the Emerson Knives...and you can take them apart without the fear you will be left in the dark.
Sounds like one hell of a nice concept to me, simplicity and functional craftsmanship.
