I have always loved SK tools especially their 1/4" drive master set , I believe it is simply the best ! I have been using them for over 47 years and still have my first sets and just gave them to our oldest grandson . About 5 years ago I bought all new sets of 1/4", 3/8", 1/2" and 3/4" drive and I Just love them. I have been using tools all my life starting at age 5 when I used my small saw to cut the 2" oak leg off of my grandmothers brand new dining room table. I have always made my living with my tools , even when I was in the Air Force building nuclear weapons . I simply love SK only problem is they are very hard to find . Some years ago I was in a big department store in Grand Forks North Dakota where they sold the complete line on the shelves just like Sears Roebuck use to do. I only wish this was the case in Florida . I wish I could get a job like you here testing tools for them , what a great job. I believe I will love your link to their catalog . Sorry this was so long . Thanks my name is Ed but go by Butch , hope to text with you again.
