All About Pocket Knives

i came upon a small penknife. the blade was inscribed richards lampost with a picture of an old lampost. on the other side was stainless sheffield england. the other one was a knife in a rather ornate leather and brass sheath. the blade says arvenpaa finland. has anyone ever heard of either of these?

HELLO
FOR THE PEN, YOU MIGHT TRY THIS NAME

THE OTHER IS PROBABLY A PUKKA OR LEIKU MADE BY ONE OF MANY
FINNISH CUTLERS. GOOD LUCK
