sharpening an OTF knife

[mccainphn]

can anyone tell me the best way to sharpen an out the front knife? I've got a GATCO & a DMT knife sharpening system, but when you put the clamp on the blade it moves around so you don't get a consistent angle on the blade, is there any way to overcome this?

Put some masking tape on the spot you clamp, it will stop the movement.
