I use the Flying Dutchman brand of blades exclusively. I have tried just about every brand out there and I always come back to Flying Dutchman. I do recommend that you try a few brands because one blade is not always suited to a cutting style. Just make sure that Flying Dutchman is one of your choices for testing.
If you have been using poor quality blades you will be surprised how big of a difference you will see in high quality blades. They are sharper and hold their edge longer. You will also be surprised to find out they are generally no more expensive and often cheaper than the lesser quality blades.
I buy all my blade from Mike Moorlack off his website. www.mikesworkshop.com .
I consider Mike a friend. Just about everyone who meets Mike considers him a friend. He runs his business with respect for his customers. He charges a fair price and his shipping speed has always been fantastic. This might sound like an ad but I don't do paid ads. I'm telling you about Mike because I trust him and his blades.
Mikes website may not be the fanciest you will ever see but don't let that fool you. He has been in business for years and he sells blade to thousands of scrollers from professional to part time scrollers.
Let me make another blade recommendation. Mike's FD-Ultra Reverse blades are fantastic. They are my go to blade for 95% of everything I cut. They produce a superior smooth cut with little reverse side splintering. They also have the nice feature of a bend on the top of the blade. I love being able to pick up a small blade and instantly know which direction is up. It sounds like a small thing but once you have it you will never want to use a blade without this feature. After you give them a try drop me an email and let me know what you think.
