Which (first) SAK to get for my finance?

Hi all, I am getting married soon and as a gift for my fiance I would like to get him his first SAK as a gift. He has spoken about getting one for years but hasn't.

My issue is I don't know which one to get. He works a corporate job but likes tinkering around the house and yard, camping, fishing and hiking. However, I don't really understand the tools so don't know which model would be best. Would love recommendations!
