The little-known life of the scarfing tool (2003) (thefabricator.com)
Just kidding, but I'm sure you get my point. Scarfing tools are pretty boring compared to the greater issues we face since 9/11. I pray for world peace right there with anybody who will listen. But then again, I've been asked many times why tools don't last or why they break after only a short time in use. When I use the word tools I mean the now-ubiquitous ceramic inserts used for scarfing the OD upset seam of tube after it's welded.
