Fish Scaler in a Pocket Knife

Many know they can easily purchase a good brand pocket knife with fish scaler from a reliable or semi-reliable vendor.  Here are most of Crumby's.  From left to right they are two Wengers, an Aitor Inox and three Victorinox.  The last two are magnetic and are attracting a dissecting blade once used to mutilate human genitalia in Wagaland.  Or so the vendor swore.  Crumby is fixing to magnetize the other four.  What good is a non-magnetic fish scaler?

Alas, Crumby has never scaled a fish with any of these.  So they can't be compared as to fish scaling efficiency.  Chances are, however, with any of them, cleaning up the knife, post scaling,  would render whatever fish scaling efficiency, anti-climactic.

Crumby's hands down favorite among the six is the Aitor Inox, a Contador of fish scalers.  That's because it has actually functional rules.  The metric is shown here.  Need to know the size of yer minnow down to a millimeter?  The Aitor Inox fish scaler is your tool.
