Wrenches are not all created equal. You've probably figured that out by now if you've ever used the wrenches that come in your sled's tool kit for anything other than breaking ice off of your axle adjuster bolts. Snap-on's Flank Drive combination wrenches are made from forged steel and are heat treated for superior strength and durability. A 7.5-degree offset on the box end gives you a better grip in tight areas. Check out Snap-on's full line of tools at www.snapon.com
