David Weir has made his fifth signing of the summer after Lyle Taylor officially became a Blade on Wednesday.
The 6ft 2ins striker joins United for an undisclosed fee from Falkirk. He signed a two-year contract, with the Club having the option of a third, after completing the formalities of a medical and international clearance.
The 23-year-old scored 29 times in all competitions for the Bairns last term, having moved up north following a spell at Bournemouth.
Boss David Weir commented: "Lyle will be a great addition to our squad. He is young, hungry and scored plenty of goals at Falkirk last season.
"We have fought off competition to secure his signature and we are delighted he has chosen to join Sheffield United."
Taylor, born in Greenwich, started as a trainee and progressed through the ranks at Millwall, having been spotted by the Lions playing for Staines Town. During his time at The Den, Taylor had loan spells at Eastbourne Borough and Croydon Athletic, before averaging nearly a goal a game for Concord Rangers.
In the summer of 2010, the forward penned a two-year contract with the Cherries after impressing whilst on trial. Taylor only made 29 appearances during his time at Bournemouth but enjoyed productive stints at Lewes, Woking and most recently Hereford United.
In July 2012, the Londoner made the switch to the Falkirk Stadium and impressed instantly, scoring a hat-trick against Middlesbrough in pre-season, in addition to a goal against Bolton Wanderers. In the regular season he netted 29 in 42 appearances, including two further trebles.
