A very simple way to pull a staple is to use the claws of an ordinary carpenter's hammer and a nail, as shown in the sketch. The staple can be removed quickly without being bent, and no damage to the material into which it was driven will result.
“Are you dejected? here is comfort. Are you sinful? here is righteousness. Are you led away with present enjoyments? here you have honours, and pleasures, and all in Christ Jesus. You have a right to common pleasures that others have, and besides them you have interest in others that are everlasting, that shall never fail; so that there is nothing that is dejecting and abasing in man, but there is comfort for it in Christ Jesus.”
–Richard Sibbes, Description of Christ
