Client told me my drywall finishing was too bumpy, so I switched to a 12 inch knife

After 5 years of using a 10 inch knife, a custom home builder pointed out the ridges in my tape coats and said I was creating extra work. Switching to the larger knife flattened everything out and cut my sanding time by half. Any other drywallers here made the switch to a bigger knife and notice a difference?

My buddy Dave fought the same problem for years until he borrowed my 12 inch on a quick patch job, came back and told me it was like driving a Cadillac after a go kart. He bought one that same week and never looked back.

And THAT'S exactly what my buddy learned too, the 12 inch just floats over the tape and doesn't dig in. The extra width lets you lay down a MUCH flatter coat without fighting the mud. Once you get used to the weight it honestly feels like cheating compared to wrestling with a smaller knife.
