A low cost testing setup

I wanted to create a simple, low cost setup that I could do some testing… this is what I came up with.

I bought a pack of utility blades. I had seen others use this to test, initially I didn’t really like the idea. But then I tried it, and realized, it’s great. Cost around $15… here’s a sample:

I found another small microscope, under $6, I thought would work a little better since it had a stand and clip:

The setup:

I can even snap a photo with my smartphone to document findings…

(That’s a factory edge, btw.)

Having a number of blades, I can number or label them, to make comparisons of finishes, look at burrs, etc… quick, easy, and at a low cost.

Just thought I’d throw the idea out there! :slight_smile:

salutes the awesomeness
pressed done too fast.
Am I seeing heat discoloration oj that edge?

Thanks. Good idea. Not only is it cheap you can also use the blades for cutting tests, etc.

I use utility blades all the time. I am interested how they sharpen up being that they are very thin compared to regular knives.

May have to sharpen some of my own for special Wick Edge precision cutting jobs. I wonder what type of steel these things are made off? Has to be cheap stuff.

Fred, that could very well be from heat… I don’t know for sure though.

Geocyclist, I’m glad you brought that up, I was going to mention that I sharpened a couple, and they come out great! Always makes me appreciate how “dull” a blade I once thought was sharp, really isn’t. :woohoo:

The steel actually seems decent… they sharpen up nicely.

I like the microscope, that’s a great simple one. How thick a blade can it hold?
Also, this looks like a great way to test and practice technique.

  • for great idea!

The clips are too weak to hold a knife very well. For that, the scope pops off the stand, and I just use it like the other scopes.
