handle and weight


It's been 15 years since I started making bankrobbers.
As you can see, the early models had thin handles, and some people said that they would break easily.
So far, we have received about 10 repairs, including broken stitching and broken zippers. I haven't had any issues with the handle breaking.
Why? Because I make it so that such a thing does not happen, but seriously, in the world of my work, there is a technical foundation for ensuring safety based on various data called breaking load (where in the world For example, there is always a crane at a construction site such as a large-scale building, and the technique for unloading is called slinging. also designed these bags. The JIS standard defines the tear strength of leather to be approximately 2.4 kgf/mm at a thickness of 0.6 mm. Based on that, the design strength of the Bankrobar is about 85kg of breaking load.
If it's for bank robbery, that's what I want, but I'd like you to assume that 1/6, or about 14kg, is the maximum load for everyday use.
14 bottles of milk is fine, but I don't want it to be aesthetically pleasing, but the weight you think you can carry is fine.


On the other hand, why is the callback bag short handle?
This quotes the tension in the wire rope of the sling, whereas the bank clover has a vertical load direction based on the size of the shoulder, which is 1x.
Since the short handle is just a grip, the tension is doubled from 90° to 120°.
What I'm trying to say is that it's easier to handle than the one with the shoulder handle.
When carrying a large object with one hand, you want to carry it in a shape that follows the direction of travel, such as when turning.
I want to avoid hitting the opponent with subtle wrist movements. Huh.
It has a breaking load of 1200kgf, so I would like people who have to carry large items in a crowd to try it once.
