Solid machine! 7/7/2017

As a knife maker I've always wanted a Rockwell Hardness tester. When I finally had my money saved I saw Grizzly was out of stock. But clicked on the email when it's available box. Pleasant surprise when a few weeks later I get my email saying its in stock. I placed my order it arrived quickly. This thing is package well and HEAVY! After carefully unpacking I was amazed how difficult it was to "unpack" the wooden blocks inside the unit. My ONLY complaint is the instructions like everyone else says are translated to English and extremely hard to follow along with. But with patience it all begins to make sense. I've sense got it "dialed" in and ready to test my first batch of knives. This machine is best described as intricate as a grand father clock made out of cast iron and steel!

Great product 7/6/2017

This item works as it should. It took a couple of tries to get the readings to match the calibration blocks. On mine, the small indicator has to point to the edge of the dot, rather than the middle, when setting the pre-load in order to have the results match the calibration blocks.

It comes with a flat plate and a V-block to test round items. The included "dust cover" is a joke, just a well fitting plastic trash bag. But there is a nice case to hold the tools, sample blocks, and anvils.

good product from china 1/26/2017

I purchased this hardness tester to check knife steel that I heat treat. Compared to all other brands this was the least expensive. I am very pleased with this tester so far and surprised me with its accuracy once it was set up and calibrated properly.
