On a serious note, you can make a decent spud bar from a 6 foot length of 1 inch water pipe by smashing one end in a vise and then sharpening it on a grinder. Put a Tee on the other end and you are ready to go. Some guys will put a rope through the tee and wrap it around their hand so they don't lose it if it goes through the ice. I do not recommend this as I have fallen through the ice and had to try and get the rope off my hand. i have a commercial made one that I bought at the fishermans shack on main street in akron 29.00. It has a solid bar with a chisel end that is very sharp. i try to make it go through the ice in front of where i step by slamming it down chisel end first. Do not let go of the spud bar on each hit. if the spud bar goes through you should back up and move left or right to find thicker ice. if you can't then it is wise to get off the ice until it is thicker. trust me, it is no fun walking back to your car soakin wet after losing all your fishing stuff through the ice cause you kept going after the spud went through. This happened to me two years ago 2,5 miles out on Lake Erie. Lost a Vexilar and around 200 worth of poles and tackle. Also, the spud can actually help you get out of the water if you do go in. Lay it out in front of you and push down on the ice to make a T shape. this works very well with snow on the ice. But, if you stop going farther out when the spud goes through you will have a much better and cheaper experience.
