Luckily this does not entirely depend on mass.
What do we lose?
If there were no Late Heavy Bombardment (LHB) the Earth's crust would be fairly lacking in what are called siderophile elements. This is too bad, there are some good elements in that list, including gold, cobalt, iron, iridium, manganese, molybdenum, nickel, osmium, palladium, platinum, rhenium, rhodium and ruthenium. We'd still have some of these at the surface, we'd just have a lot less of them. The Earth is still bombarded with space rocks, the LHB was just a significant portion of that bombardment over the last four billion years.
It's hard to say how much of what we would have or how the abundance affected abiogenesis or evolution of life. So, we'll assume life still developed in the same way, but we wouldn't have the rich deposits we have now.
So what do we have?
We'd still have lithophile elements and, to a lesser degree, chalcophile elements. Some of the metals we'd get are aluminum, tungsten, and titanium in decent quantity. We'd get a little bit of copper, lead, and tin. It's not a bad start, it gets us through the bronze age. The iron age would be a problem. Because our own timeline would be halted in pre-history it's quite difficult to say where humans would have gone from there.
I find it unlikely we'd figure out the refinement aluminum, tungsten, or titanium without the tools and knowledge developed during our collective experience with iron. Those are difficult metals to refine in comparison to iron.
The technology we'd be able to develop then would be things we hardly consider technology. Things like spears, hatchets, bowls, and other cooking tools. We'd have wheels and fire. We'd have some woodworking and stoneworking tools. We'd have concrete, but wouldn't have a great method for reinforcement. We'd have glass, though it wouldn't be very high quality.
Again, these are all things that modern people don't usually consider technology. Even though we'd have the elements to make things like microchips, we couldn't develop the required infrastructure.
It'd be a simple world.
