I have ordered blades from J.Hittle several times in their 10 pack & the blades are pretty good. I have no complaints with them. I assume they are the same blades as the 100 pack but you could call him & ask. Several years ago when someone here posted about the Harbor Freight blades, I bought some & they worked great. I repeat bought them online about a year & all the sudden they wouldn't cut & were terrible. I thought I had a bad batch so I had my sister pick me up some at her HF store. They also was terrible. They must of changed their suppliers or something but at first they really was great blades. I also recently bought some from Ormkraft & I really like the blades & they have good prices.
