"Lame" is the fancy French name for a blade used to score bread prior to baking. This version is straight (as opposed to some version where the blade is bent in an arc).

To assemble:

• 2 x [M4x12 flathead screws] (https://www.homedepot.com/p/Prime-Line-M4-0-7-x-12-mm-Grade-A2-70-Metric-Stainless-Steel-Phillips-Drive-Flat-Head-Machine-Screws-10-Pack-9121152/311229692)
• 2 x [M4 nuts] (https://www.homedepot.com/p/4-mm-0-7-Stainless-Steel-Metric-Hex-Nut-2-per-Pack-800998/204274078)
• [Standard double-edged razor blades] (https://www.amazon.com/Dorco-ST300-Platinum-Double-Blades/dp/B001MJSAJQ/ref=pd_lpo_3?pd_rd_w=93bsb&content-id=amzn1.sym.116f529c-aa4d-4763-b2b6-4d614ec7dc00&pf_rd_p=116f529c-aa4d-4763-b2b6-4d614ec7dc00&pf_rd_r=7AGR636Q5Z59V98B77NX&pd_rd_wg=ohdtc&pd_rd_r=81c30dd5-a07a-4128-ab28-3883c3258a08&pd_rd_i=B09SBQZ1CN&psc=1)

The blade will just get sandwiched between the halves with the two screws through the end and middle hole in the razor.

Happy baking!
