It's a Wonderful Knife is a 2023 American Christmas slasher comedy film directed by Tyler MacIntyre and written by Michael Kennedy.

It stars Jane Widdop, Jess McLeod, Joel McHale, Katharine Isabelle, William B. Davis, and Justin Long.

After The Angel briefly chases Winnie, she learns that the town's sheriff is now Henry's younger brother Buck, who claims he does not recognize her.

Winnie goes to see her family, who also do not recognize her, and she realizes she has been transported to an alternate reality in which she never existed, meaning that The Angel is still alive and has already killed several more people since the previous year, including Jimmy.

The website's consensus reads: "It's a Wonderful Knife takes an enthusiastic stab at holiday-themed horror-comedy, even if it doesn't cut quite as deep as it should.

[10] Chicago Sun-Times's Richard Roeper gave the film a score of two and half out of four, writing "As you'd expect, It's a Wonderful Knife is filled with blood-spattered twists on holiday movie tropes.

The genre slant promised by the title seems to be less of a tonal responsibility than an excuse to abruptly break out into the occasional suspense set piece".

He ended his review with "The film is defined by an overruling superfluousness — it's the sort of thing people might be satisfied with watching from the corner of their eyes while wrapping presents".

[12] Meagan Navarro of Bloody Disgusting scored the film three out of five and said "MacIntyre's latest may not quite seamlessly nail its high concept genre mashup, but with some outstanding performances and a sweet gooey emotional center, it effectively tugs at your heartstrings and captures the spirit of Christmas".

[13] Robert Daniels writing for RogerEbert.com gave a score of three and half out of four, "It's A Wonderful Knife has plenty of attributes—charm, blood, and angst—that should fit right in at any family holiday gathering".
