The blades on hockey skates are only as sharp as the wearer has honed them. Professional ice skates (hockey skates included) are very sharp and are honed after every session. If there is contact, the blades can cut flesh. Guards are put on the blades immediately after coming off the ice. Blades that are dull are not as fast on the ice. Being cut with the blade of a hockey skate is not a primary concern of athletes.
