Sorry not familiar with that kit or part. I'll offer that whenever I need to be carefull cutting piecesI always use a new #11 blade. I go very slowly and sometime I even use a heated blade to mention through the sprue.

I use a chisel blade to remove details I'm going to replace with PE.

Are you talking about molded on parts? If so, I use a Dremel tool with a small cutting bur to remove the molded on parts. If you remove too much plastic just fill in with putty and sand smooth.

Be very careful! Don't use a lot of pressure when cutting the unwanted detail off with an X-acto square-end chisel blade. If you apply very little pressure and gently rock the blade horizontally, you can eventually cut the part free without marring any surrounding detail. Work your way all the way round the detail, so you have a clean parting line, always cutting toward the center. If you use a lot of pressure, you risk a broken blade, or the plastic coming free very suddenly, with a loss of control of the knife (which may then gouge the surface or even bury itself in your other hand--I've got a scar to prove it). It takes a few minutes more, but you save lots of time you would have spent repairing the damage done by more destructive removal methods, like saws or power tools.

If you use the chisel blade upside down it will reduce the chance of the blade digging in.

THank you Gerald, I was wondering how much pressure should be used... and Darren, what you mean use it upside down? Mauro, the a tradizional razor blade looked scared to me, I might be the victim first.....before I cut off the parts...

I understand
It's a pity...

Firstable razor blades are cheap

Furthermore you can cut easily the blade (with a common pair of scissor) and you can change its shape

for exemple:


...or instead:


To avoid fingers injuries I use masking tape


But anyway, as i said, i understand your fears

+1 on this as well. I use a micro-chisel to get rid of unwanted detail. Works for most things but there are times I need my 11 blade to do the job.

What I ment was you should place the bevel against the model rather than the cutting face. In other words instead of holding the chisel as you would when using it on wood, you must turn it over and rest the bevel against the model. This will enable you to cut the raised plastic details off of your model without the blade trying to dig into the surface.

I use a detail remover chisel from Micro Marc. The edge has rounded corners to prevent accidental gouging.

The real benefit of this method is it also allows for the removel of large raised detail in segments safely without having to attack it all in one go.
