I gave mine a first test run today.
I tested it up against a BSA Hot Spark, using an Eriksson 511 as the scraping blade.
How many strikes until a fire started is the comparison.
First initial observations, is that the BSA Hot Spark puts off a lot of small sparks very easily, but the Mish. Metal Rod puts off fewer, but they are bigger and burn noticeably longer.
The Mish. Metal rod REALLY needs to be longer, or have some sort of handle attached. As it is, it is almost to short to use. I ended up holding it with pliers for the test.
The BSA Hot Spark, consistently sparked throughout the test, while the Mish. Metal Rod did initially, but after the outer darker coating was scrapped away, the shiny exposed metal underneath quickly dropped to only sparking about 1 in 4 strikes, and shaved curls of metal off the rest.
I tried a few different types of tinder, starting at the top left:
1. Paper from my shredder.
2. Toilet Paper
3. Dryer Lint
4. A mix of dried leaves and grass.
1. Shredder paper.
BSA Hot Spark 12 strikes to fire.
Mish. Metal 2 strikes.
2. Toilet Paper
BSA Hot Spark 6 strikes to fire.
Mish. Metal 3 strikes.
3. Dryer Lint.
BSA Hot Spark 3 strikes to fire.
Mish. Metal 1 strike.
4. Leaves and Grass.
BSA Hot Spark FAILED, not matter how long I tried, they just were not catching.
Mish. Metal finally started a fire, after nearly an hour of trying.
Here is where I ran into some concerns with the Mish. Metal Rod. Once the outer darker part was scrapped away, the shiny surface underneath, began to spark much less. And throughout this hour, they shavings that did ignite, were sticking to the blade in little balls of molten metal, and would not reliably fall into the tinder.
Here is a picture that I circled some of them in yellow, that are still orange and hot when I took the picture.
This happened a lot, and to ignite the leaves and grass, it took nearly an hour and I used up probably 40% of the Mish. Metal Rod.
I'm a little mixed on these results, the burning sparks sticking to the blade, were a real problem, I just could not get them to fall onto the tinder very well.
When they ignite, they are pretty fierce sparks though.
