It's ABSOLUTELY PHENOMENAL at $12! They work exactly like the $35 Tamiya cutters and completely destroy the $20+ Vatcan Prime cutters. They don't cut as cleanly as the USAGS Single Blade, but they dull after just a few sets and still amaze me. You can't come close to this quality without AT LEAST spending double! I would recommend lubricating them with WD-40 (but I recommend this for all cutters).
