Hitman HD Pack

This secret achievement is called "Jack the ripper" and it's for getting a successfull kill with each of the 3 "knives" in the game. It should be noted you don't have to get the kills in the same mission. You can get 1 kill with each knife across 3 separate missions but it should be also noted that if you obtain your knife and get your kill, then leave the mission or die it won't count. In other words you HAVE to finish the mission after you kill someone with the knife if your going to do this cumulatively. If you just collect the knives and get all your kills in one mission then you don't have to finish or save because the achievement will pop after the 3rd kill.

So where are the knives? Good question I'll tell you. The first is the kitchen knife located in the first mission "Anathema". The fat lady cook has it in the kitchen. Kill her and take her knife then kill someone else. Next is the combat knife wielded by the weird sadist Russian torture guy in the mission "tubeway torpedo". Interaction with him in this level in inevitable since he's sorta busy with your objective. Once you kill him take his knife and go slice a throat. Finally the scalpel which isn't a knife so I have no clue why it's considered one but hey the world's not exactly perfect. Anyway the scalpel is in the mission "terminal hospitality" and it's down in the basement. There are actually several in this mission so you should find one laying around quite easily. Now just go kill another innocent (or guilty) victim and claim your gamerscore.
