K & H Wedges are the toughest wedges you will find!

They are used for keeping the plank from pinching the bar and chain

Since 1962, K&H have been making wedges to give professional tree surgeons a non-sparking lightweight wedge that is tough and durable. These larger wedges keep planks from pinching the bar and chain as you are milling. If you want a quality felling and general purpose wedge this is the one to buy.
