Wait, sorry this is about bandsaw blades. Carbide tipped bandsaw blades are the bomb until they break and you realize what you paid for them.
I've had those carbide tipped blades welded back together several times with good success.
Back in 1976 there was a flood disaster in Eastern idaho when a damn broke. Wiped one city right off the map and flooded two more cities with 4-5' of water. I worked on that mess for a few months, but when we first started there was no power. Only generators.... I had all my hand tools with me and hung a lot of blank doors and set trim completely by hand. I had all the work i wanted because my dad taught me to set finish by hand proficiently before he let me use the power tools. That experience came in handy during that time.
later on in 77 we were framing a bunch of houses and the weather got bad, and work ran out. So i decided to move indoors and contracted the finish work for a few homes. At that time i had no power finish tools of my own, or finish nail guns. So i set up my hand miter saw, sharpened my chisels and block plane, bought some finish nails, and rolled up my sleeves.
The home builder was so impressed with my skills by hand, he started bringing his home buyers in to see my "Old School" workmanship, and loaded me up with work. I had people waiting an extra month to have their finishwork set by hand, and the builder even paid me 25% more for my work too.
But truth be known.... by the time i finished a dozen houses i did purchase a power miter saw and finish nailers for other projects in the future. Kirk
