English: Cutting nails with a sawsall tool. This was a project to repair stairs; but the nails between the stair and the riser were thin and hard to get up. When hammers and crowbars won't work, you can use a sawsall tool (shown) to cut through the unseen nails. The blade extends a few inches under the top stair. Be careful of kickback (if the blade hits something else). Source of picture: here (see public domain declaration at top).
