Never ceases to amaze me how metallurgy affects our everyday life. My wife loves to sew. She makes the most beautiful things. She has worn out two fine sewing machines. A German Pfaff machine is a real fine machine. But she has managed to wear em out. The other day she was complaining that it is almost impossible to buy a safety pin that actually works. She said the wire used in safety pins is soft and the pins do not work as well as pins from years ago. I just ignored her comments as she said the safety pins sold these days are all made in China. Well I have been a tool maker and gunsmith for over 50 years now. I have made all sort of parts and pieces. My small machine shop keeps me busy and in "beer money". Just finished a set of safety rail splices for a stainless rail system. The material was 316 stainless. Not a real hard material but tough. Finished all the machining and had to cut the newly turned and machined parts in half. Grabbed a hack saw and started sawing. The cut in the stock was barely a sixteenth deep when my hacksaw blade gave out. Removed the first blade and installed another. Same thing! Barely a 1/16" cut and that blade was done as was a third. They all went into the scrap metal bin. Went and looked in the supply cabinet and beside the new shinny blue blades was a Nicholson hacksaw blade. I installed it and proceeded to saw right through my 3/4" piece of stainless. Looked at the teeth on the Nicholson and they still looked good. The blue blades were nicely made and painted blue with MADE IN CHINA marked on them. These should have been marked for wood only not metal. I call any Chinese knife, saw, drill, spring, file, or cutting tool all junk! They are made out of a rare element not even on the Periodic Chart of Elements. The element is Chineseieum. Anything made out of it rusts, disintegrates, bends, breaks, and falls apart! I have made a vow to never buy Chinese tools, cutters, drills, or files. The CCP are destroying out finely made manufactured goods and putting American manufacturers out of business. The middle class working tradesman is suffering because of the cheap china goods flooding our shores. I took a photo of my hacksaw cutting. Three china blue junk blades! Soft as butter.
