On my KTBHs I leave follower boards which are 3/4" thickness at the rear most position. This gives me enough room to slip a thin stainless rod bent at a 90 degree angle about 1" from the end down the sloping side to separate the comb in an up lifting motion. Don't ask me how I know up is better!

Stainless because it has more strength in a small diameter than anything else I have used.
