Spare Blade for Bench Dog No. 4-1/2, No. 5-1/2 and No. 7 Planes
This blade is a direct replacement for the one included with Bench Dog® Tools No. 4-1/2, No. 5-1/2 and No. 7 bench planes (#50258, #54865 and #58682, sold separately). Having a spare iron on hand ensures you'll always have a sharp edge to deal with challenging grain, and you can also purchase multiple blades and grind each to a different bevel angle to suit a range of applications. The blade is made from 1/8'' thick hardened carbon steel for reduced chatter and excellent planing characteristics.
- Fits Bench Dog No. 4-1/2, No. 5-1/2 and No. 7 bench planes (#50258, #54865 and #58682, sold separately)
- 1/8'' thick carbon steel for chatter-free performance
- May require honing

A-2 and O-1 are both tool steel alloys, and as such, they have improved hardness and toughness, but at the cost of a coarser crystalline structure. What this means to you, the woodworker, is that an A-2 blade will stay "pretty sharp" longer than an HCS blade, but it is possible to achieve a keener edge on an HCS blade due to the finer "grain" of the steel.
For myself, I use A-2 for most of my planes because fewer sharpening sessions means more time spent making shavings - hooray! ... BUT, my smoothing planes only use good quality HCS blades, because once I got practiced at producing a "scary sharp" edge on my tools, I found that I could indeed get that little extra bit of sharpness that allows me to take whisper-thin shavings and leave the wood as smooth as glass, right off the plane. "Look, Ma, no sandpaper!"
