Nothing wrong with carrying the "equivalent tools" to a multitool every day. In fact, that's what the multitool evolved from -- trying to cram the essence of that functionality into a single package.

You can certainly get the same functionality in stronger tools, for less money, but with more bulk.

In my younger days, I rarely carried a multitool with me on my solo backpacking trips. I could assemble equivalent "capabilities" and save several ounces. And in situations where you carry everything on your back (and are responsible for others' welfare too), those few ounces are better spent on backup clothing etc.

The thing about a good multitool is that I have it within reach at all times. There are more powerful tools in my car in the parking lot, in my shop, etc. etc. Every "kit" I have has better tools. But if I'm on the 30th floor of some office tower, they might as well be on Mars.
