10-in-1 Multi-Function Whetstone Camping Tool - Survival Knife Sharpener, Fire Starter & Outdoor Gear for Hiking, Backpacking & Bushcraft Adventures

I love this tool! It comes in handy for everything when camping. It is solidly built and will last a long time. After sharpening it, it cuts very well - both knife and axe. It is long enough that the axe/hammer can be swung to be effective. Of course, you won't be chopping any large logs with the axe but it sure is fun to use for smaller projects. I comes with a fabric case that keeps it tucked away neat. The blade of the axe is on the edge of the case, uncovered, so be careful not to let the kiddies fish it out of your bag if it is sharp! I l've used the file, bottle opener, different knife blades, and screwdrivers. The only down side I can think of is that of course - the hammer has some weight to it. It is as heavy as any small finishing hammer head so it probably wouldn't be the best choice if you are going on long hikes/ back pack trips. Works great for me to carry in my day pack to use around the campsite, on day hikes, to mess with around the camp fire, and on the 4-wheeler just in case (for what I am not entirely sure! But it is great to have around when you need it)
