Odd looking chainsaw bar

[Mark71GTX]

I was working on an Echo 302 and it has a strange bar on it. At first I thought it was worn strangely, but the roller tip seems to align with the odd shape. The end of the bar reminds me of a kitchen knife. It is an Oregon bar. The numbers (best I can tell) are RC 25922 and below that 440SZAA041. Is this an oddball or have I lived a sheltered life

It is what is called a banana bar, Poulan used them for years. The radius design was intended to reduce kickback. Your picture shows the bar upside down.

Yeah, doing it from my phone would not let me edit it. Thanks for the info. This is the first one I have seen.

McCullough used them also, and replacements for Poulan come that way too. You should be able to find an aftermarket replacement (Oregon too) in standard configuration, allowing it to be flipped once in a while for even wear.

I make my own fence rails and posts out of black locust. Had this bar on a small Sears saw I used for boring the holes in the post for the rails after the post is set into the ground. It worked really well to reduce kickback when starting the cut.

Old post, but here's what I know. They were invented in the mid 70's by a saw mechanic at the BCFP camp in Port renfrew BC. I was on the forestry crew in that camp. We were the test dummies. The originals were solid tips, you couldn't flip your bar, and the chain would throw way more often.

Thanks for the follow-up. I have came across dozens of these bars since that post. Each and every one of them have gone straight to the scrap pile.

Sorry to keep adding to this old thread, but I did see a bar like that a short while ago. It was on an older Echo CS-300 EVL. Here is a picture from the manual regarding the bar.
