Croaven

This is something I have wanted to see since the day I purchased the game, and frankly, anyone who thinks this would be op has never made or used a bow drill. It would not be hard to balance it out. First you would need to find the right kind of wood which currently would only be salvaged wood since you can't use cedar or fir wood to make them. (If someone has had success making a bow drill with conifer wood please correct me but I have been unsuccessful in creating a working one out of wood with a high pitch content.) Second, they are time consuming to make with the types of tools you have access to in the game. You need a block of wood for the base, the drill, sinew, and bone or a stone to apply pressure to the drill. All of these would have to be found and shaped to fit their purpose. Make it so each individual part has to be crafted before combining them together. Third, they are difficult to use even if you know what you are doing. You absolutely have to have tinder to start a fire with a bow drill. You should not be able to use one in game without it. It would not work with just kindling. It also takes a great deal of effort which would translate to calorie usage in game. It would also have to have a low success rate even at higher skill levels (60%-70% max). And the fire starting time would be much longer than any other fire starting means. Fourth, they are heavy. This would add a decent amount of weight to your already overloaded pack and would force you to make some difficult inventory decisions. Fifth, you could easily balance this by making it an item that can only be effectively used at the highest skill levels, and even then make it have low success rates. Sixth, It can also be like the other crafted tools where it can't be repaired. So each time it breaks you have to go through the time consuming process of hunting down materials and making another one. It may take some tweaking but it would not be difficult to make this a balanced part of the game.
