I do a little tree climbing, and the saw I take in the tree with me is a Stihl MS192T. It’s a great little saw, not as powerful at the MS200T, but enough to do what I need. However one shortcoming it has is the integral plastic bucking spike. The plastic teeth are too short, ill shaped, and just plain too dull to dig into the bark.
While browsing the parts manual for this saw, I noticed one of the images showed a separate bucking spike and chain catcher. The spike part number is 1129 664 0500, and you’ll also need two of the special screws, PN 9074 477 4130.
