I'm a full time taxidermist and have used a ton of different blades over the years.I have a bag full of custon knives for skinning and caping,maybe 12-15 of them.I don't want to calculate how much I have invested in them.A few years ago I bought two of the Pirantas with orange handles and carry them,several blades and a couple pairs of 6 mil,nitrile gloves in a baggie,whenever I'm out and about.I love them-and they are easy to thoroughly clean.
I love the custom knives and still use them occasionally but these days with my old eyes,I'm not as keen on touching up blades in the field,especially after dark.A couple years ago I shot a 350 lb bear just before dark and had to skin it and quarter it on the ground,by myself in the dark with a hoard of mosquito's tearing me up.The Piranta came in handy and I got through the job with 2 blades.I'm picky about the sharpness of blades.
If I remember,the Piranta weighs about 1 1/2 oz.I used to carry 3 custom knives and they weighed at least 2 lbs plus take up more room.The piranta has its place.
Use it with respect.The blades are very sharp.I think the new,thicker blades would be even better.
