This early 70's giallo by Umberto Lenzi is certainly among the best in his filmography and also in the whole genre. Personally I think Lenzi's best films are the funny cartoon-turned-film Kriminal, the stylish giallo Seven Blood-Stained Orchids, the explosive Napoli violenta and this. In the eighties he did plenty of film trash in form of Eaten Alive, Hitcher in the Dark or Black Demons, all of which are ripping something off and/or very dull and slow moving. Knife of Ice came when the giallo boom was at its hottest and the result is convincing.
　　Technically the film is superb, containing great cinematography in the beginning when we learn about the main character's trauma towards trains. From this point on, Lenzi shows us his ability to benefit the widescreen and, for example, the bicycle ride near the forest is genuinely beautiful! This scene also shows Lenzi's ability to build suspense, very slowly but meaningfully. After all, there aren't so many murders in the whole film, only the suspense circulating around the murderer's identity.
　　One suspect is a devil worshipper which brings new aspects to the mystery. Since the final scene takes place in a church, one can wonder if Lenzi wanted to comment on something, maybe the hypocritical morale of church and superstition. The main character (Carrol Baker) is mute which demands a lot from her face and eyes. The actress works very well, giving us a believable performance circulating around the emotions of fear and mental pain. The other actors are good, too. The finally, however, may not give too positive a sight about female sex since they all are expressed rather negatively in the film, one way or another. Still this is easily among the most noteworthy in the genre, not as bloody as the Argento films, for example, but equally suspenseful and visually also interesting.

　　影评:此电影虽然不太出名，但却获得过国际影展六项大奖，被称为次世代恐怖悬疑片的里程碑。本片以极低的成本拍摄出了好来屋级大片效果，无论是画面还是声效都极具震撼力，阴柔的灯光特效和演员的演技将影片所表现出的恐惧绝望感发挥的淋漓尽致，骇人听闻的故事内容（情节与人物名字皆参考圣经）与离奇的怪物设定也是本片的一大看点。此片悬念部分做的非常出色，片子把所有伏笔都埋在了最后，所以不到最后一刻你是不会知晓事件真相的，到时影片所展现出的魄力绝对会把观众震惊。
