I see others have used Fiskars and are happy with them. I feel like I only get half the use out of them as Olfa. Ebay usually has Olfa for a fairly good price. I might try Harbor Freight sometime, but I cut a lot of nylon tricot with them so not sure how they would hold up. I bought a rotary sharpener at Joanns and it works ok. They are never as good as new, but they work good for awhile. Especially if there is just one spot that won't cut.
