Ask an adult to cut the blade out for you.
You might also try a single edged razor blade for cutting if you do not have an Xacto or hobby type knife available.
Select the correct blade for the material you are going to cut.
Keep this in a safe place until the blade can be reattached, or reattach it to the mower without the blade for safekeeping, if you can do so on your model.
If you cut the material at home, you may want to buy a new blade for your saw while you're at the store to make a clean cut.
There are people out there who will stick a blade into you for £20 and a mobile phone - or because you looked at them in a funny way, or didn't show enough "respect" - and don't care if you live or die.
We use Victorinox knives with black plastic handles and a seven-inch blade (for bigger fish such as salmon you might need a longer blade).
Feed the marble to the saw slowly and let the blade do the work for you.
Set your saw at low speed and let the blade do the work for you.
If you have a large amount to move, you may want to rent a small tractor with a front end loader bucket and a grader blade or box blade to do this job for you.
