A blade guard for a circular saw blade of a power driven saw, wherein the blade guard is configured to partially cover a rear face of the saw blade while leaving an opposite front face of the saw blade uncovered, the blade guard comprising: - a guard plate configured to partially cover the rear face of the saw blade, the guard plate having an inner face configured to face the saw blade and an opposite outer face; and - at least one elongated shielding unit fixed to the guard plate and configured to cover a part of the peripheral edge of the saw blade, wherein the blade guard is open along a section of the periphery of the guard plate in order to allow a segment of the saw blade to project from the blade guard beyond this section, characterized in that said shielding unit comprises a holding structure fixed to the guard plate and several shielding elements fixed to the holding structure and arranged side by side along the shielding unit, each shielding element comprising a shielding member and a resilient cantilever support member having an inner end and an opposite outer end, wherein: - the shielding members of the shielding unit are arranged side by side in a row in order to form an elongated barrier that is configured to prevent cutting debris formed during a sawing operation from being ejected out of the blade guard; - the support member of each shielding element is fixed to the holding structure at its inner end; - the shielding member of each shielding element is fixed to the associated support member at the outer end thereof and resiliently connected to the holding structure via this support member, such that the support members of the shielding unit allow the shielding members of the shielding unit to move in relation to each other and in relation to the guard plate when the blade guard is pressed against a surface that extends essentially in parallel with the guard plate. - a guard plate configured to partially cover the rear face of the saw blade, the guard plate having an inner face configured to face the saw blade and an opposite outer face; and - at least one elongated shielding unit fixed to the guard plate and configured to cover a part of the peripheral edge of the saw blade, wherein the blade guard is open along a section of the periphery of the guard plate in order to allow a segment of the saw blade to project from the blade guard beyond this section, characterized in that said shielding unit comprises a holding structure fixed to the guard plate and several shielding elements fixed to the holding structure and arranged side by side along the shielding unit, each shielding element comprising a shielding member and a resilient cantilever support member having an inner end and an opposite outer end, wherein: - the shielding members of the shielding unit are arranged side by side in a row in order to form an elongated barrier that is configured to prevent cutting debris formed during a sawing operation from being ejected out of the blade guard; - the support member of each shielding element is fixed to the holding structure at its inner end; - the shielding member of each shielding element is fixed to the associated support member at the outer end thereof and resiliently connected to the holding structure via this support member, such that the support members of the shielding unit allow the shielding members of the shielding unit to move in relation to each other and in relation to the guard plate when the blade guard is pressed against a surface that extends essentially in parallel with the guard plate. - the shielding members of the shielding unit are arranged side by side in a row in order to form an elongated barrier that is configured to prevent cutting debris formed during a sawing operation from being ejected out of the blade guard; - the support member of each shielding element is fixed to the holding structure at its inner end; - the shielding member of each shielding element is fixed to the associated support member at the outer end thereof and resiliently connected to the holding structure via this support member, such that the support members of the shielding unit allow the shielding members of the shielding unit to move in relation to each other and in relation to the guard plate when the blade guard is pressed against a surface that extends essentially in parallel with the guard plate.
