2 Pc 7", 8" or 9" PL10 Straight & Curved Hair Grooming Shears Set

I've had these for about 5 weeks and I've already had the curves worked on and sharpened. The straight cut extremely different then the curves which for a set is very odd to me. These were only purchased to have a back up while my quality pair were sent off and honestly there's a good chance I will just throw these away when I get my good pair back.
