Interesting flash removal tool

I just ran across these, and was thinking of purchasing.  Has anyone used this product?  (I am not affiliated with them in any way whatsoever)

Flash Master flash removal blades

Never seen such a blade.  Let us know how they work.

I don’t see what advantage the flexibility would provide? If it came with a permanent curve and double edged maybe?

x2...  Not sure putting enough pressure on the blade to make it conform is good for most seam or flash removal.  But, I haven't tried it so I guess I'm no judge.

Been using X-Acto type blades my whole life without a problem so don't see the need for this. Looks like you'd have to master a different approach in using this but maybe it will work better for some.

I had never heard of them, but I am not sure what the flexing would do either. Now, if it could be curved, and holds its' shape, then maybe that would be different. My concern is that the flexing would cause it to go in an unplanned direction. Also, the cost seems very high

I’ve noticed when I scrape flash/seams on certain types/hardnesses of plastic, I get a sort of “bar code” effect along the seam, which I then have to sand out. If the flexibility of these blades stops that happening, they might be worth a look...

Hi Jonathan,

This is Jon from Flash Master Hobby.  I originally designed the blades for the trimming of flash on injection molded figures.  The slimness and the flexibly have huge advantages and allow you to get at the most hard to reach flash with less force, which translates into more control.  BUT, I'm not a model car buff, so I can't give specific examples of how it would help you - but I can say that the blade carves polystyrene so effortlessly that I have to believe that there are many applications in your end of the hobby.  In fact, I'm looking for people in different areas of expertise to give them a try so I can get their feedback and answer questions like yours.  If you're up for it, I could send you a free pack of 10 for you to check out and see if they are useful to you.  If you are interested, please message me on our Facebook page!

Interested but I will not have anything to do with Facebook. Thanks anyway.

What you are describing is familiar to anyone who has used a lathe.  It is called chatter and it is cause by the cutting tool flexing and rebounding.  On that basis I would say that this is not the tool for you. 

By the way, the best way to remedy the problem you describe is to change the angle of the blade from perpendicular to the seam.  One pass perpendicular, one angled left and then one angled right.  You do that because chatter becomes more pronounced with each pass.
