The tool kit is useless. Get the specific tool for your purpose. The bracelet tool looks fine and in the 'related products' there is a punch set for pin bracelets that looks good.
A good screwdriver set is handy, I've used one like this for years,

You can spend a lot more if you like but for us dilettantes this works well. Buying tools is a slippery slope, have fun. :)
