Russian to English Social Sciences Archaeology Paleolithic

This part of the text is discussing the formulating of archaeological terms into the Russian language. The full paragraph from which this is taken is as follows:

Основной вклад в формирование современной русской терминологии внесли Ф. К. Волков (переводя монографию Нидерле, он разделил скребки от скребел; до того термин "скребки", иногда подразделяемые на "широкие" и "узкие", охватывал обе эти категории) и П. П. Ефименко, предложивший термин "ручное рубило" вместо "топора".

Both terms can be rendered as "scraper", but this paragraph talks of distinguishing between two different kinds. My technical dictionary gives for скребло: "scraping knife", and for скребок: scraper, scrubber".

So could I get away with "...to distinguish between a scraping knife and a scraper"?

This site gives some definitions of different types of scraper:
