Can I fit the 64-bit driver fit in the old Pro Toolkit?

So, I took a look at the new Pro Tech toolkit, and compared it to my existing Pro Tech Toolkit for reference. I currently own the version with the 54-bit driver kit, I don't really see a reason to get it. I do however, see a reason to maybe get some of the extra tools it comes with and adapt my classic Pro Tech Toolkit over time.

Would I be able to say, get the 64-bit driver kit and put it in as a drop in upgrade later on if I need to replace enough tips in it it's more economical to upgrade my screwdriver set? As it is, the bit variety the 54-bit comes with is nice. I like it, since most of my previous tools are scattered and incomplete.

The reasons I ask this, is because as Mayer pointed out it makes more sense to replace it once you lose or damage multiple bits over time.(I don't remember where this was mentioned specifically but it was said.) However, I'm not 100% positive if he mentioned how many it takes to reach the point professionals and economic scrooge hobbyists would replace it even with most of the bits being there, so I took a look myself. I worked it out to 4 bits at $11 total with each bit costing $3 rounded from $2.95 a piece. It would cost $5 to ship 4 bits, which was initially $11. You're looking at $16.80 to replace screwdriver tips, when a complete set is $20 for the 54 bit driver kit. The economics to replace bits just doesn't make sense if you lose or break multiple bits in one shot, which is going to be the more common situation.

Now, let's look at individual bits if you replace them as you go, or you get spare bits. You pay $3 for one bit each, or whatever spares you buy. You pay $3 for an individual bit, and the shipping is $5. Using these numbers, it's $8 to replace one tip individually. You do this 4 whole times, and you're in the same situation as the multiple bit situation. Due to this, it's logical to only replace it if you use it. If it's not a bit you use a lot or at all, you would be better off going without it. If you lose multiple unused bits, then the case goes from one bit to multiple, and you're running into the same problem because you chose to use common sense and save your money. The economics to replace individual driver bits is not good. Even if you replace them individually, it literally costs you more over time to replace bits, when you can get a new driver kit later on after you lose enough to justify it.

As a professional in the IT field, I know this all too well. There are times I have lost tools in the field, broke things or simply left them at the client's place of business/home. When it comes to toolkits, we're probably not going to replace the tools if we don't use them at all, or a lot and can replace them with something else that's similar. For example, my old DVD drive.

One day, it decided to fail me when I needed to use it even with a few USB cables so I got frustrated and completely destroyed it out of annoyance. Instead of replacing it I took it as a lesson and decided replacement can wait. This gave me time and forced me to think of another option since I can't put the replacement off forever since I will need it sooner or later. The solution is a generic case that looks similar to my old one, for $8. Since I have a drive that will work I'm just going to go the route of reusing an old IDE DVD drive that I have not used in years to make some space. This is actually viable, and I'm going to try it. If it works, I can get another one and put the other IDE drive I have to use. In this case putting it off saved me money. This is just one example why professionals tend to wait, and why situations like the bits for the 54-bit driver kit costs to replace bits happen so much.

In regards to the pry tool upgrade, that's something I will have to do later on down the road, since they will wear out and I will need to replace them. At some point, I'll have those. That's not a concern. On another note, the spudger upgrade is welcome. If I break one, then this one means I am screwed. The backup is welcome.

As to including the Jimmy the solution there is to simply buy one down the road, and put it in the existing tookit.

The removal of the tech knife was in my opinion, ridiculous. That knife is very useful, and taking it out reduced the value of the new toolkit in my eyes.
