I use the toothed iron as a scrub plane to hog off, flatten and remove any twist. It’s a lot easier than using one of the other irons. Once I have a board flat I run it thru the planer to clean up both sides. To get a completely smooth finish on the face I either use a scraper or the Veritas scraper plane. When you buy another plane you’ll get another 25° so camber one and keep one flat. However, I hardly use the 25°. I use the 38° to finish side grain and the 50° on the shooting board to finish end grain.

Changing the pitch. It’s like – why? With the 25-38 & 50 you have what you need.

For tearout … keep the mouth open just slightly and most of all plane with the grain.
