I broke my curved set at the hinge joint & decided to try these. The size is great for grabbing those small screws that seem to drop down into small recesses on a engine block or for holding small pins to get them started with a punch when Vise-Grips/needle-nose pliers are too large. These have the locking features & serrated jaws. Made in Pakistan out of Stainless Steel. A bit on the large side if one was to use them for suturing flesh. Quality is great for a shop tool & they're inexpensive to boot. Come in non-sterel packaging.
