I think if you look at a particular knife and determine the side pressure that might possibly cause a blade to be pushed into an adjacent blade, you would be able to figure it out. On the whittler I posted yesterday, the thing to do would be to open the master blade to the full open position first...get that sucker outta the way. Then you can open the secondary blades at will with no chance of rubbage.
I know it's a repost but, for the sake of illustration...on this 5-blade stockman...
....you need to open the master blade first...then work your way from the inside out. You would next open the blades that were closest to the master blade.
