Do we need flexibility or are we committed to a specific approach? If versatility is necessary, then best to carry a Swiss Army knife. If we are certain, then a flat head screw driver will work. But if drop the screw into a tight space the tweezers on the knife would be helpful. Or, if we need to read small print the mini-magnifying glass could be handy. At a certain point, even the Swiss Army knife cannot possess all the options. So, how certain are we that we have the right tool for the job? A specially designed instrument can be a powerful resource. A pair of alpine downhill skis will get us to the bottom of a ski hill fast. However, if we need to ascend the mountain afterwards, the skis are a major liability. Unless we have an alpine touring setup with climbing skins and a binding that transitions to climbing mode.
Specialized equipment or multi-tools? A good question to ask before we launch on our next adventure.
