This blade: A2, 1 3/8" wide, 5/8" slot width, #BWA138. It seems the block plane is the workhorse of many cabinet shops. Although taken for granted, this is a very handy and versatile tool. And, like the larger bench planes, it responds well to a better blade and a little TLC.

Which one fits my plane?
Hock block plane blades are available in two widths: 1 3/8" for Stanley-style low-angle planes and 1 5/8" for the 9 1/2 and similar planes. And there are two slot configurations: 5/8" wide slot for newer Stanley planes and 7/16" narrow slot for older planes. There are two alloys to choose from: high-carbon steel or cryogenically treated A2 tool steel. A2 is recommended for bamboo fly-rod makers, as it holds up much better to the abrasiveness of bamboo.
A2 blades have an "A" in the part number.
Hock makes its plane irons in two types of steel:
O1 – high-carbon steel that is easier to hone and gets sharper
A2 – cryogenically treated tool steel that holds an edge longer
Both are a big improvement on the thin blades supplied with many new planes. A2 is recommended for hard and abrasive materials, such as bamboo. If you sharpen often and want the keenest edge, O1 is a good choice.
Hock block plane blades are 3/32" thick and 4 1/4" long and fit Stanley and Record block planes. You choose by width and slot:
Width: 1 3/8" for Stanley low-angle block planes and 1 5/8" for the No. 9 1/2 and similar
Slot: 7/16" for older planes and 5/8" for newer Stanley planes
Measure the slot in your old blade before you order. The blades come in both O1 and A2.
There are several good ways to sharpen chisels and plane irons: water stones, diamond stones, oil stones and sharpening machines such as Tormek. All give sharp edges, but they differ in speed, maintenance and price.
A honing guide makes it easier to keep the same angle every time. The most important thing is to find a method you enjoy and use often. The guide helps you choose.
Planes of cast iron and steel rust easily, especially in unheated workshops and from moisture on your hands. Wipe the plane after use and protect bare surfaces with a thin layer of wax or oil that will not mark the wood.
Store your planes dry, ideally in a plane sock or box. If rust has already formed, the guide shows how to clean and protect them.
A new replacement iron can make an old plane better than it was when new. To find the right one, measure the iron's width, thickness and slot dimensions, and check whether the plane has a cap iron and what kind of adjuster it has.
A thicker iron chatters less but may require the mouth to be adjusted. The guide shows how to measure and choose correctly.
