Honestly, Strength already was my dumpstat in SR5: Shock Gloves and Stun Batons were a better choice for me, allowing me to ditch Strength like crazy. Physical Limit was the only reason I put at least some karma into it. As for katana: Since its description said it was a 2-handed weapon, a Sword was by far superior in SR5. But then again, you'd only carry a blade if you were a melee fighter (aka Adept with a Weapon Focus), since otherwise guns and unarmed were a better choice (unarmed for the smuggling-in part, guns for distance).
