I've never attempted, however have witnessed first hand flounders being caught with a knive. Simply slowly aproach stab into sand, get hand under the fish and grib the blade * must use gloves as to not cut your hand!!!
Catching flounders, or even monkfish, with a knife is easy. Stab them near the spine just a little behind the head. Knife sideways, or the fish will swim off it, splitting itself in two. I use a regular cheapo non-diving knife, no lanyard, no retention system and never need to grip the blade. Never lost a fish. If the first stab doesn't kill the fish, hold it still in the sand and use a second knife or let your buddy finish it off.
Should work well with the California Halibut as well as it is much smaller than the average monkfish. Catching wolffish with a knife, now that's for people with cojones muy grande...
