Plane blade steel conclusions

Bill Tindall, E.Tn.
Results of work: Feet planed before sharpening was needed for the various steels.

Conclusion: PMV11 planes more feet, etc. I wish the conclusions had been summarized and published.

For my case the significant metric is not how many minutes a day are saved. By this metric it matters not that one steel lasts 30% longer, or some such.

Given the way I work and the kind of planing I do(never more than a minute or two at a time) what matters is how many unanticipated times I need to sharpen in the course of building a project. If I can cut one of these annoyances out each time I build something it becomes important to me. Hence, David's work was useful to me.

As a bonus he answered the question, does a highly refined edge last longer than one not quite as refined, another curiosity of mine. Thousands of feet of stuff was planed in the course of this work. I'm indebted.
