When I first started scroll sawing and I ,of course, needed some blades, I went to Lowes and Home Depot. They usually have everything so why no blades? lol
Lowes didn't have any but Home Depot did and so I bought them. I now wish that I knew about Flying Dutchman blades before I bought them.
My experience is..... There is not a large variety of sizes available.
There were mostly PINNED ones. So I had to purchase a multi pack to get different sizes and UNPINNED ones.
I finally decided to purchase some FD ones after reading posts in here. I am glad that I did because there is a LARGE variety of sizes and the prices are better!
So now I purchase those. I think I will stick with FD blades because I am satisfied with them.
I use different SIZES. One day I will purchase some spiral and reverse blades.
But remember... To Each Their Own.
Do what YOU feel is best for YOU. Good luck hun.
