Re: Why Are Plane Blades So Expensive?

Small-time iron makers dont have the same economies of scale that higher volume chisel makers do. Let's say a person wants to make chisels and they get say $50 apiece for them (the present market pretty much dictates a ceiling here). They probably have to sell at least 200 a month to keep things rolling. Their costs will be relatively high... they can either coordinate the activities of a number of small shops or they will have to capitalize significantly. Materials costs are relatively low but, processing costs are high. In addition their are specialized processes involved (handling, ferules, edge squareness, etc.), Assembly operations, and thus, an INVENTORY to carry and coordinate. Up until LN's recent technology vault, the materials and processes were reasonably constant. Chisel makers have more complicated design and packaging issues.
On the other hand, small time iron makers have to make relatively small design modifications to ensure their product fits exisiting plane designs. Most are laser-cutting and thus, the inventory issue is greatly reduced. A low-cost supply of tool steel, a stamp, simple packaging, low capital investment (mini-Bridgeport) make this a relatively easy market to get into. The other thing that can really affect the cost of an iron is the chip breaker (requires more processes than the iron) and if one is being authentic, the screw that joins them (not typically available). Having said all of this, the small time makers and hobbyists have had a significant impact on the market forcing the development of irons (tool steels, cryogenics, etc.) and chip breakers. Who knows what kind of an impact small time players would have if they were able to participate commercially in the chisel market? The small time players developed irons and the larger entities had no option but to follow and why not - they make better margin with their economies of scale!
Then there's the numbers... How many retrofit plane irons are sold annually in North America? ... and how many chisels?
