Cheese said:I've been curious to try a Blue Spruce bench chisel for a while now. They did what I consider was a no-brainer, they polish the back of the chisel to a mirror surface and provide the chisel already sharpened with a primary bevel and a 5º micro bevel. I've wondered for over 20 years why manufacturers didn't provide that service as part of their product?
It's the equivalent of purchasing a new car and having it delivered to you with the plastic still on the seats, the cardboard still on the carpets and the various stickers and wax stick markings still on the windows. [sad]
Here's a comparison between a Pfeil that I've always used and the Blue Spruce...notice the price I paid for the Pfeil, I paid $129.99 for the Blue Spruce.
The BS chisel blade comes completely coated in a Dip Seal like material. The blade is A2 tool steel, double tempered and then cryogenically hardened.
The top of the Pfeil blade appears to have a roughness value of about Ra 125 µ-in, while the BS blade is around 8 µ-in, maybe a little bit less.

However, the bottom of the blade is where the real difference comes in. The BS is beautifully polished, it's pretty amazing. Here are a couple of bottom photos to compare. Now I need a project to try it out on.

I have one of their paring chisels and it's the same. Really nice stuff. As an aside. .most people only need the first inch polished. I polished the full back of my LN's though because I'm OCD. They aren't mirror but they're darn close.
