Normally, what a tool looks like isn't really relevant. When you first see the Birzman Light Er 9 11 Speed Portable Chain Tool, however, you can't help but admire the craftsmanship. There are good reasons for the beauty of its components. The tool is CNC machined, which ensures the precision and durability of its metal parts. The varnished wooden handle makes the tool more comfortable to use and keeps the weight down. Speaking of weight, the tool only weighs 81 grams, so it will be a welcome addition to your pack or seat bag. The Light Er chain tool also incorporates an innovative spring system that secures the chain during breaking and makes it easy to drive the pin out accurately and easily.
