A2 or HCS?

A2 or HCS?

Denis Chénard, Orléans, Ont.

>Tonight I attended a seminar titled "The Plane Truth" at Rosewood Studio. Ted Brown, the owner and program director, gave us quite a detailed presentation (which was free, BTW, all that was asked for was a donation to the local food bank or local charities).

I learned so much, me, a rank amateur when it comes to handplanes. Actually it was the first time that I've seen a pro in action using his planes. Quite an eye opener...

Of course, since Rosewood Studio also retails tools they didn't mind if they made a few tool sales, but that's OK, no one got a plane blade pressed to his/her throat... The sales that I've seen were of plane models used in the seminar.

But...

Like most of us, I suppose, Ted Brown has his list of preferences. He seemed to prefer HCS blades over A2 for its ease and speed of lapping the blade's back, and he thinks he can get a keener edge with HCS, even if, by his own assessment the edge doesn't last as long as with A2.

Somehow when I restored/upgraded/tuned up my small collection a couple months ago, I did not feel a marked difference between the two. In all fairness I didn't time the process, but I didn't get out of the shop feeling that I spent more time on A2 vs. HCS. Any expert wants to weigh in on this?

Other observations: Brown feels he can the smoothest surface with the wooden planes he builds (hey, he studied under Krenov), but seeing him using his planes seemed a bit too finicky for me (at least for now). He also mentioned that he's not a fan of bevel up planes, and that the traditional, bevel down planes can make a smoother surface.

I don't want to put Brown on the spot, I am very appreciative for the seminar he gave. Yet I feel that some of his statements are like BMW vs. Mercedes, both are great and do the job, but one of the two just happens to "feel better" in your hands...

>I dunno Dennis.

I "feel" that the edge on my A2 blades *does* last quite a bit longer than the hcs (of which most of mine are) but I guess I can't put a number on how much.

His opinions on bevel up planes are simply wrong - I feel strongly about that. I own a small army of handplanes - many Norris, every model of Bedrock you name it - but my "go to" plane is the Lee Valley L.A. jack equipped with either the standard blade for endgrain or the 62 degree bevel for gnarly face grain.

Bevel up is here to stay.

See Steve Elliot's web pages for the answer

>And another Krenov student, David Finck, Hand plane Book, sells and swears by A2 irons.

Fortunately, Steve Elliot has done a definitive study of these issues and provides quantitative comparisons on his web site.

Bottom line, all the tool steels can be sharpened to the same degree. Abrasion resistant steels can be more difficult to sharpen with improperly chosen materials but their edges lasts longer-no surprise here!

Walnut or cherry?

>Asking the question of high carbon steel (HCS) vs A2 (air hardening steel) is like asking which wood is best for a project. Too many variables. Every steel has a composition. Every steel is hardened. Steels of similar composition which are hardened to the same specs perform in a similar fashion. Finding the right steel for a particular application involves picking the right composition and hardening to the appropriate level. This is why it is often best to trust manufacturers of blade products. They have done testing and have validated their process.

>I agree with Bill. My experience is that A2 lasts longer and can be sharpened to the same level as HCS. I know that HCS blades vary in quality and I have read as much for the A2 blades. My A2 experience has been limited to LV and LN blades neither of which seems to best the other IMO. I too prefer HCS blades. Conceptually I look at woodworking as being a system that includes tools, woods, techniques, and traditions. In my system, I prefer to use oil stones for sharpening for a number of reasons I won't go into here. HCS is much easier and faster to sharpen with oil stones than A2 though both can be sharpened with them. I go to diamond media far more for A2 steel. Your instructor has framed his opinions based on his system of work, which I believe he communicated to the class. He didn't give you Universal Truth. He gave you his truth.

>Hi Denis,

Mark me down as one who, though I have planes with both, if I have a choice it is HC every time.

Which ever steel is in a plane, I sharpen just as frequently, which is more often gauged by the tasks. Neither ever really get dull. I don't let them. Pop them out and hone during use. Same with chisels.

But for me it takes fewer strokes to do the HC than the A2.
