Constructing: riveting knife together

When you snip off the pins a point is left behind that will make riveting more difficult, so always file the end of the pin flat before you start to hammer

• file one end of the pin flat, push it through the knife until it is flush with the surface then snip off the other end as close as possible
• supporting the other side on a flat surface, file off the point then start to rivet it over, turn and rivet a little the other side, then turn again and rivet the other side again - keep turning and riveting until the pin feels secure
• the pivot pin needs a long, tapered countersink to hold it secure - start by tapping directly in the middle of the pin to spread it into the countersink lower down before working around the edge to fill the test of the hole - pause frequently to open and shut the knife to make sure the rivet does not get so tight it pinches the blade between the liners
• the middle and end pins are under less pressure so just need mushrooming over by tapping around the edges
