Other than weight, what are the differences between say a regular Husqvarna sprocket nose bar and one that costs three times as much from another manufacturer?
Cannon & Sugihara make the world's best.Bar none.Quality of steel & no shortcuts in manufacturing. Cannon still made by hand in Vancouver Canada since 1955.Not cheap but worth every cent.
Will the average chainsaw guy really notice a difference? Longevity of bar, speed, oil dispersement, etc?
My question about the "tall" profile of the Cannon bars: Does it provide a straighter cut for racing? and is the secondary advantage a few more drive links added to the chain?
Aside from the 'super premium' brands, here's the basics ... Your basic, entry level bar has laminated construction and an integrated sprocket nose. Next up the line, the steel gets better, the bar is one piece and the sprocket nose becomes replaceable. IMO, for the average cutter, a name-brand bar with a replaceable nose will last for many years with proper care.
Most chainsaw users will destroy a saw before the bar is even 50% gone. The trend (outside of the enthusiast community) is towards disposable bars because the practice of "dressing" a bar or re-grooving one is all but extinct. I haven't tried any of the super-premium brands yet but that's mainly because I have yet to wear out even a laminated bar on any of my saws.
Even the laminated bars without replaceable tips will last many years & they are usually lighter than solid bars.
There is a big difference in rail wear from cannon and tsumura to oregon and some of the others. Milling will show it in 2-3 cuts on some oregon bars. I probably got 200 bd ft and needed a dressing on an oregon and a tsumura cut the same thing with no noticeable wear.
^This^ I kind of wanted a Sugihara 28" for the weight savings, but the cost wasn't worth it to me, so I just picked up an Oregon bar. I doubt I'll ever wear it out just cutting firewood and while a 28" bar is heavy, it's not the end of the world for the handful of times a year I'll use it. A buddy of mine just had a Stihl bar for his 028 redressed this year. It was bought by his wife's grandpa and used on the farm for 30 years before it was worn enough to need re-grooved. So I'd say a stock bar is fine for most of us, unless you got the money burning a hole in your pocket fore something prettier.
Not that, but has something to do with having just one north American distributor that was retail/wholesale and maybe old inventory?
