Both factory forged and hand forged blades are often laminated. A thin layer of very hard steel (traditionally [[crucible steel]] made from [[limonite]] iron) is sandwiched between two layers of softer metal, which make the blade less brittle and facilitates repeated sharpening. Before the 19th century, almost all iron in Finland was made from limonite on charcoal blast furnaces, which yield very pure and high quality iron suitable for crucible steel. Today both carbon steel and tool steel are used. The blade can be lightened and strenghtened with a fuller. | Both factory forged and hand forged blades are often laminated.

The traditional material for the handle is [[birch]]. Also [[oak]], [[ash (tree)|ash]], [[pine]] bark, horn (especially elk and reindeer), [[scrimshaw]] and bone are used. Often the handle is made from various materials between spacers. Today, however, industrially made puukkos often have plastic handles. | The traditional material for the handle is [[birch]].
