“…An increasing k was successively responsible for the continuous and significant (P < 0.05) increase in cutting work for the samples BC, PC, and SL. This contradicts literature results for the forces which occur during conventional cutting of food and nonfood products (e.g., Atkins et al, 2004;Marsot et al, 2007;Shin et al, 2003Shin et al, , 2006 without ultrasound.…”

“…The capacity of a tool before it must be honed or sharpened is related to cutting edge retention and resistance to wear and usually denoted as cutting performance. Cutting performance is a function of some intrinsic properties of a knife or a blade: the alloy used for making the tool, and inclination, geometry, curvature, and the sharpened edge of the blade (Marsot et al, 2007). These intrinsic properties can be optimized as long as the material which is subjected to the cutting process is of a homogenous nature.…”

“…As a result of these factors, our experimental protocol also allows for large, robust sample sizes to be collected. Notably, the use of materials similar to those used here has been extensively documented within engineering and ergonomic literature as accurately replicating the conditions of a number of biomaterials during hand-held cutting tool use (e.g., McGorry, 2001;Claudon and Marsot, 2006;Marsot et al, 2007;Gilchrist et al, 2008).…”

with cutting efficiency using both flakes and handaxes over extended periods of use and in multiple types of cutting task. Results indicate that (1) both handaxe and flake cutting efficiency is significantly related with biometric variation of individual tool-users, (2) relationships between biometric parameters and efficiency are consistent across extended durations but vary dependent upon task-type conditions, (3) manipulative strength is the most significant biometric trait in terms of predicting flake efficiency, while (4) hand size is the strongest predictor of handaxe cutting efficiency. These results demonstrate the long-term impact that stone tool use likely had on the evolution of hominin biometric variation during the Lower Palaeolithic, while also highlighting the variable influence of different tool use contexts.Most notably, results indicate that the onset of the Acheulean may have been dependent, a priori, upon hand dimensions that are close to the modern human range, and that prior to the appearance of this anatomy, handaxe use would have been an impractical (i.e. inefficient) tool use behaviour compared to the use of flakes.

“…Several parameters such as cross‐sectional design, helical and rake angles, angle incidence between instrument and sample (Marsot et al . ), hardness of the alloy consequent to electropolishing or heat treatments and instrument motion influence the cutting efficiency of NiTi instruments (Peters , Giansiracusa Rubini et al . ).…”

Aim To compare the cutting efficiency of several glide path files: HyFlex EDM Glidepath File (HEGF), One G (OG), R‐Pilot (RP) and WaveOne Gold Glider (WOGG) at different cutting inclinations. Methodology Cutting efficiency of 120 new HEGF, OG, RP and WOGG was tested at 90°, 70° and 45° inclination in relation to the sample. Depending on manufacturer instructions, instruments were tested in continuous rotation or reciprocating motion against standardized gypsum samples for 120 s using a customized apparatus. Cutting efficiency was determined by measuring the weight loss and the length of the sample cut. Data were analysed using two‐way analysis of variance and Tukey t‐test (P < 0.05). Results RP and WOGG had greater cutting ability than HEGF and OG in all tested angles. RP tested at 45° had significantly greater cutting efficiency than when tested at 90° and 70° (P < 0.05). OG was not significantly different in terms of cutting ability at 90°, 70° and 45° (P > 0.05). HEGF and WOGG had significantly greater cutting efficiency at 45° and 70° compared to 90° (P < 0.05), with no significant difference between 45° and 70° (P > 0.05). RP had the greatest cutting ability at all tested angles. Conclusions Reciprocating glide path instruments had greater cutting efficiency compared to those in continuous rotation. An inclined insertion (45° or 70°) increased the cutting ability of glide path files except for One G conventional NiTi files.
