I did a dozen for giggles earlier today.
The pistol grip really do give a better leverage. The grip is comfortable, but because it is form shaped, I don't know if it would be still be comfortable one's hand is very small or very large. For me, it was slightly bigger than perfect.
The thin blade body made it easier to insert the knife in to cut the adductor muscle. The tip helped at reaching to the bottom of the shell to cut the bottom attachment point.
The only minor gripe I have is I can use a slightly shorter blade body. I don't usually shuck large oysters.
I am as much of a nut about my kitchen tool as I am about my knives. As a result, I have used quite a few different oyster knives.
This is the best one I own right now.
P. s, they say it does clam pretty quick too. I am going to get some to try
. I have a clam knife that you pull towards you to open the clam, but I find that it often mess up the flesh.
