Wicked saw

[RedMF40]

Never seen this design.

 

[38 Sears Roebuck]

I've seen that before but I have no idea what they were thinking designing something like that.

 

[T.R.K.]

Isn't that called a 'bow saw' (or some such.) I would think slightly less likely to pinch the bar, but I bet there were times they sawed clear through and then couldn't get the saw back out.

Powered bow saw. Mainly used for tree pruning and bucking firewood from pulp wood sized logs.

Tho you can still buy them, the bars and chains. They are not as popular as they once were.

 

[MarkB_MI]

Most saw manufacturers recommend against using bow bars due to their high kickback risk, but they're still available from third party suppliers. Mainly for bucking firewood.

Used them extensively cutting Christmas trees. That dog on the end controls the kickback.
