When you say "work on" do you mean modifications or disassembly?
The ZT 0900 blade is under 3''. If you can go 3 1/4 or 3 1/2'' you choices would increase quite a bit.
Ok, let's say maximum blade length of 3 1/2" and can disassemble without voiding warranty. But would prefer a shorter blade.
Can't go wrong with a Benchmade mini Griptilian or mini Barrage.
Take a look at the ZT line. There are a ton of choices with blades 3 1/2'' or less. You can take ZTs apart without voiding the warranty. How much are you looking to spend?
